What to check when buying a car: step-by-step checklist for

Buying a car is always a risk, even if you purchase a new car from an authorized dealer. And in the secondary market, the likelihood of running into hidden problems or legal pitfalls increases significantly. According to statistics Rosavtodor, every fifth used car in Russia has serious technical faults or problems with documents that the seller is silent about. At the same time more than 30% of buyers do not check the car’s history through official services, relying only on a visual inspection and the words of the seller.

This article will help you avoid common mistakes when buying a car. We will look at what to check first, what details to pay attention to during inspection, how to recognize a twisted mileage or a “drowned car”, and also what documents the seller should have on hand. Let us separately dwell on the legal nuances - for example, how to check whether a car is pledged or wanted. The instructions are suitable for purchases from individuals and car dealerships (including trade-in).

1. Checking documents: what the seller should have

The first and most important stage is studying the documents. Without them, a deal is impossible, and any discrepancies should raise red flags. Start by checking vehicle passport (PTS). It must be an original (not a copy), without erasures, corrections or signs of forgery. Please note:

• 📄 VIN code match in the PTS, registration certificate (STS) and on the car body. Discrepancies are a sign of a broken number.
• 🔄 Number of owners. The more there are, the higher the risk of hidden problems (for example, the car could be used as a taxi or rented).
• 📅 Date of issue of PTS. If the document is new and the car is older than 5 years, this may indicate that the title has been replaced after an accident or theft.
• 🚗 Make, model and year of manufacture. Must match the actual vehicle. Sometimes the PTS indicates a “younger” year in order to hide the truth.

Also ask the seller certificate of registration (CTC) and his passport. Check if the owner’s details in the vehicle title and passport match. If the seller is acting under a power of attorney, make sure it is notarized and not expired. Since 2026, powers of attorney for the sale of cars without notarization are invalid - this is a common trick of scammers.

Additionally check:

• 📋 Sales and purchase agreement (if the car was purchased previously). All previous owners must be registered in it.
• 💰 Tax receipts (if the seller is a legal entity). Their absence may indicate problems with the Federal Tax Service.
• 🔧 Service book (if there is one). You can use it to track your service history and actual mileage.

2. Legal cleanliness: how to check a car for liens, arrests and accidents

Even if the documents are in order, the car may be burdened with debts or be wanted. You can check this through official services:

Service	What does it check?	Cost	Link
Traffic police (website)	Accident history, search, registration restrictions	Free	traffic police.rf
FSSP (Data Bank of Enforcement Proceedings)	Arrests, bans on registration actions	Free	fssp.gov.ru
Register of pledge of movable property	Availability of collateral from a bank or credit institution	Free	registry-of-pledges.rf
Autocode, CarVertical	Full history (mileage, accidents, repairs, taxi)	From 300 ₽	avtocod.ru

Pay special attention checking for collateral. If the car is pledged, the new owner will not be able to re-register it until the loan is repaid. According to United Credit Bureau, in 2023, every 12th used car in Russia was sold with an unpaid loan. Also check:

• 🚨 Search — if the car is listed as stolen, it will be confiscated after purchase.
• ⚖️ Registration restrictions - for example, due to unpaid fines of the previous owner.
• 💥 Accident history - if the car has been in a serious accident, this may affect its safety.

What to do if the car is pledged, but the seller promises to repay the loan?

Never trust verbal promises! The only safe option is to conduct the transaction through the bank that issued the loan. They may offer a “deposit on purchase” scheme, where the money goes first to closing the loan and then to the seller. If the seller refuses this option, refuse the purchase.

If you are buying a car from a dealer, ask warranty obligation in writing. This will protect you if it later turns out that the car was pawned or wanted. In the case of individuals, it is better to draw up purchase and sale agreement subject to verification of legal purity and indicate that the transaction is considered concluded only after confirmation of the absence of encumbrances.

3. Body inspection: how to identify hidden damage and repainting

The body is the “face” of the car, but serious problems can be hidden behind the beautiful appearance. Start your inspection with a check body geometry. To do this:

1. Open and close all doors, hood and trunk. They should open/close without effort, without squeaks or distortions.
2. Look at the gaps between the body panels. They should be the same along the entire length (usually 2–4 mm).
3. Check that the body lines match at the joints (for example, between the fender and the door). If not, the car has been in a serious accident.

Next, inspect paint. Signs of repainting:

• 🎨 Different shade on different parts of the body (especially noticeable at different light angles).
• 🔍 Roughness or bubbles - a sign of poor quality repairs.
• 🧲 Paint thickness gauge will show layers. The norm for most machines is 80–120 microns. If more than 200 microns, the body was painted.
• 💡 Traces of putty - tap on suspicious areas (for example, wings) with a plastic pen. A dull sound indicates putty.

Please note hidden cavities (spars, sills, pillars). Rust there may not be noticeable, but can lead to serious problems. Use a flashlight to see into hard-to-reach places. Also check:

• 🚗 Bottom — traces of corrosion or fresh anticorrosive treatment may indicate off-road driving or frequent trips through salt.
• 🔥 Welding marks - if they are, the car was restored after a serious accident.
• 💧 Humidity in the cabin or trunk - a sign that the car was sinking or stood in the rain for a long time with the windows open.

If you are not confident in your skills, order pre-sale diagnostics in a car service. The cost is from 1,500 to 5,000 rubles, but it is cheaper than repairing the body after purchase. This is especially true for cars older than 5 years or with a mileage of more than 100,000 km.

4. Engine and transmission: signs of wear and damage

The engine is the most expensive component in a car, so you need to pay maximum attention to checking it. Start with cold start (when the car has been standing for at least 6–8 hours). Please note:

• 🔊 Engine sound - should be smooth, without knocks, creaks or “diesel” rumble (a sign of wear on the piston group).
• 💨 Exhaust color:
  • 🔵 Blue smoke — oil enters the combustion chamber (wear of rings or valve stem seals).
  • ⚪ White smoke — antifreeze in the cylinders (the cylinder head gasket is broken or there is a crack in the block).
  • ⚫ Black smoke — over-enriched mixture (problems with the fuel system or turbine).
• 📉 Oil and antifreeze level - if the oil is black or has metal shavings, the engine has not been serviced for a long time.

After the engine has warmed up, check:

• 🔥 Temperature — if the needle quickly moves into the red zone, there is a problem with the cooling system.
• 🛢️ Leaks — inspect the area under the car for stains of oil, antifreeze or transmission fluid.
• ⚙️ Gearbox:
  • For Automatic transmission: Shifts should be smooth, without jerks or delays.
  • For Manual transmission: There should be no crunching noise when shifting gears or spontaneous shutdown.
  • For robot/variator: listen to extraneous noises (humming, grinding).

Be sure to check computer diagnostics. Connect the scanner (for example, ELM327 or Launch CReader) to the connector OBD-II and look at the errors. Particularly dangerous:

• 🚨 P0300–P0308 — misfires (problems with spark plugs, coils or compression).
• 🔥 P0171/P0172 — lean/rich mixture (may indicate a malfunction of the sensors or air leaks).
• ⚙️ P0700–P0799 — problems with the transmission (this is critical for automatic transmissions).

If you are not skilled in diagnostics, take an experienced mechanic with you or pay for a service check. The cost of engine diagnostics starts from RUB 2,000, but this will save you from the risk of buying a car with a “dying” engine.

5. Interior and electrical: what to pay attention to

The interior can tell as much about the car as the engine. Start by checking general condition:

• 🪑 Seats - abrasions, tears or signs of repair indicate high mileage or use in a taxi.
• 🎛️ Steering wheel and pedals — if the steering wheel is worn out and the pedals are almost new (or vice versa), the mileage could be off.
• 🚗 Smell - the musty smell of mold indicates that the car was sinking or stood for a long time in a damp place.
• 🔊 Noise insulation - if it is missing or damaged, the cabin will be loud and cold.

Next check electrical and electronics:

• 💡 All light bulbs — low/high beam, dimensions, brake lights, turn signals.
• 🔊 Audio system - turn on the radio, Bluetooth, check the speakers.
• 🌡️ Climate control/heater — check all airflow modes and temperatures.
• 🔋 Battery — the voltage at the terminals should be 12.6–12.7 V when the engine is off.
• 🚗 On-board computer - if it is “buggy” or shows errors, problems with the ECU.

Please note additional equipment:

• 📱 Multimedia system - if it is not original, check if the firmware is “crooked”.
• 🚨 Alarm — ask how it works and check all the functions.
• 🔑 Keys — there must be two of them (if one is lost, replacement can cost up to 20,000 ₽).

Don't be lazy to check all buttons and levers — from adjusting seats to heated mirrors. If something doesn't work, it could be a sign of problems with the wiring or control unit.

6. Chassis and brakes: how to assess the condition of the suspension

The chassis is something that directly affects safety. Start with visual inspection:

• 🚗 Wheels — check the tread wear (should be even). If one side is more worn, there are wheel alignment problems.
• 🔧 Shock absorbers - press on each corner of the car. If it swings for a long time, it’s time to change the shock absorbers.
• 🛠️ Anthers and covers — cracks on the boots of CV joints or steering rods indicate an imminent repair.
• 💧 Leaks — oil stains on shock absorbers or struts are a sign of their malfunction.

Next check braking system:

• 🛑 Brake discs - should not have deep grooves or “ripples” along the edges.
• 🔧 Pads — the thickness of the friction layer must be at least 3–5 mm.
• 🚗 Braking efficiency - When braking sharply, the car should not pull to the side.
• 💡 ABS — when braking on a slippery surface there should be no vibrations or knocks.

Be sure to drive your car along different types of roads:

• 🛣️ Smooth asphalt — check whether the steering wheel is shaking or whether the car is pulling to the side.
• 💨 Pits and hummocks — listen for knocking noises in the suspension (they may indicate wear on the silent blocks or ball joints).
• 🔄 Turns — the car should not tilt or creak.

How to check the steering rack?

Ask the seller to turn the steering wheel all the way in one direction or the other with the engine off. If you hear knocking noises or the steering wheel is stiff, the rack requires repair or replacement. Also pay attention to the steering play: if it is more than 5–10°, this is a sign of wear on the steering rods or rack.

If you are not confident in your skills, drive the car to lift or to a service center for a complete chassis diagnosis. The average cost of such a check is 1,500–3,000 rubles, but it is cheaper than repairing the suspension after purchase.

7. Mileage and service history: how to recognize twisting

Twisted mileage is one of the most common sales tricks. According to Autostat, in 2023, every third used car in Russia had low mileage. How to identify this?

Indirect signs of twisting:

• 📉 Interior condition - if the mileage is 50,000 km, and the steering wheel and pedals are worn out, as after 200,000 km.
• 🔧 Service book - if the mileage is 150,000 km, and the odometer is 80,000 km.
• 🛠️ Condition of consumables - if spark plugs, belts or brake pads have never been changed with “low” mileage.
• 📄 History on sites - for example, on Autocode or CarVertical you can see the actual mileage based on the data from the service station.

Direct signs:

• 🔍 Signs of tampering with the dashboard - if the panel was disassembled, the mileage may have been twisted mechanically.
• 📊 ECU data mismatch - some scanners (for example, Launch X431) can show the actual mileage from the control unit.
• 📅 Vehicle release date - if the car is 10 years old and has a mileage of 30,000 km, it is almost certainly damaged.

If you suspect twisting, ask the seller to provide checks from service station or data from on-board computer (if he keeps track of mileage). You can also check your history via VIN code on the manufacturer's websites (for example, Toyota, Volkswagen or Hyundai provide data on official dealers).

8. Test drive: what you must check while driving

A test drive is the final check before purchasing. It should last at least 30–40 minutes and include different driving modes. Here's what to look for:

• 🚗 Starting the engine - should be fast, without prolonged cranking of the starter.
• ⚙️ Gearbox:
  • For Automatic transmission: shifts should be smooth, without jerking.
  • For Manual transmission: There should be no crunching or difficulty shifting gears.
  • For variator: listen to extraneous noises (humming, grinding).
• 🛣️ Behavior on the road:
  • The car should not pull to the side when driving in a straight line.
  • There should be no vibration or beating in the steering wheel when braking.
  • There should be no squeaks or knocks when turning.
• 🔊 Noises - pay attention to extraneous sounds (knocking, creaking, humming).
• 🌡️ Engine temperature — the arrow should not go into the red zone.

Also check:

• 💨 Air conditioner/stove - must work in all modes.
• 🔋 Electronics — check all the buttons, heaters, power windows.
• 🚨 Brakes — the car should brake smoothly, without pulling to the side.

If the seller refuses to let you drive the car or limits the route (for example, “only through yards”), this is a reason to be wary. It may be hiding problems that appear at high speeds or during long periods of driving.

After the test drive, inspect the car again for leaks (oil, antifreeze, brake fluid) and check wheel temperature - if one wheel is hotter than the others, there is a problem with the brake caliper.

FAQ: Answers to frequently asked questions

❓ How to check a car for theft?

Check the VIN code through the traffic police database (traffic police.rf). You can also use the services Autocode or CarVertical. If the car is stolen, the transaction will be declared invalid and the car will be confiscated.

❓ Is it possible to buy a car without a PTS?

No, that's impossible. PTS is the main document for a car. Without it, you will not be able to register the car. If the seller says that the title is “in the bank” or “lost,” this is a reason to refuse the deal.

❓ How to recognize a “drowned person”?

Signs of a flooded car:

• Smell of mold or dampness in the cabin.
• Traces of rust under the seats or in the trunk.
• Wet floor mats or condensation on windows.
• Non-functioning electronics (power windows or audio system often fail).
• Dirt or sludge under the hood or in hard-to-reach places.

❓ What to do if after purchase it turns out that the car is in collateral?

If you have already signed a purchase and sale agreement, but it turns out that the car is pledged, you have several options:

• Demand termination of the contract and return of money through the court.
• Agree with the seller to repay the deposit (if he agrees).
• Contact the bank that issued the loan and try to transfer the collateral to yourself.

In any case, don’t delay your decision - the sooner you start acting, the higher the chances of getting your money back.

❓ Is it necessary to draw up a purchase and sale agreement with a notary?

Since 2026, notarization of a car purchase and sale agreement is not mandatory, but is recommended in controversial cases (for example, if the seller is acting under a power of attorney or the car is expensive). However the contract must be in writing and contain:

• Passport details of the seller and buyer.
• Complete vehicle data (make, model, VIN, body/chassis number).
• Transaction cost (if you indicate the real amount, you will not have to pay tax on the difference).
• Date and signatures of the parties.
