In a world where inflation eats away savings and bank deposits barely cover losses, the issue of preserving and increasing capital becomes critically important. Car owners feel this especially acutely: the car loses 20-30% of its value immediately after purchase, and maintenance costs increase annually. But what if we say that there are things that not only do not get cheaper, but also bring hundreds of percent profit in 5-10 years?

This article is not about abstract stocks or cryptocurrencies - we will focus on tangible assets, which can be purchased by any car enthusiast. From rare parts to collectible cars, from vintage tools to unique license plates, here you will find 12 tested categories, which historically show an increase in value. Important: we do not give financial recommendations, but only analyze market trends based on auction data and expert assessments.

Why is this important for car owners? Because many of these assets are somehow related to the automotive industry. Not only will you save money from inflation, but you will also be able to turn a hobby into a source of income - for example, collecting rare parts for your car or investing in models that will become a rarity in a decade.

1. Collectible cars: which models are growing in price faster than inflation

If you think that collectible cars are only Ferrari 250 GTO for $70 million, you're wrong. The classic car market is democratizing: now even budget models from the 1990s can bring 15-20% annual returns. The main thing is to choose the right brand and modification.

According to the auction house Bonhams, over the past 5 years the prices have increased the most:

  • 🚗 JDM cars (Japanese domestic market cars) 1990s: Nissan Skyline R34, Toyota Supra Mk4, Mazda RX-7 FD3S. The reason is limited export to the US/Europe and cult status in movies/games.
  • 🏁 Hot hatchbacks 1980s: Volkswagen Golf GTI Mk1, Peugeot 205 GTI, Renault 5 Turbo. Demand is fueled by millennials nostalgic for their childhood.
  • 🛒 "Barn Finds" (cars found in garages): even rusty ones Mercedes-Benz W123 or BMW E30 after restoration they are sold with a markup of 300-500%.

The key trend for 2026 is rising prices for pioneering electric vehicles. For example, Tesla Roadster (2008) increased in price from $50k to $250k+ in 5 years due to its status as the “first mass-produced electric car.” A similar situation with BMW i8 (2014) - its price increased by 40% in 2 years.

📊 What type of collectible cars are you most interested in?

⚠️ Attention: When buying a car “for growth”, avoid models with body problems (for example, Alfa Romeo GTV rots in the arches) or engines that are difficult to restore (for example, rotary Mazda RX). Restoring such cars can eat up all potential profits.

2. Rare spare parts: how to make money on parts for classic cars

The market for spare parts for older cars is growing at 12% per year, faster than the collector car market itself. The reason is simple: owners of rarities are willing to pay thousands of dollars for original parts that have long been out of production. Here are the top 5 categories where you can make money:

CategoryExampleAverage price (2026)Growth over 5 years
CarburetorsWeber 45 DCOE for Alfa Romeo$1,200–$2,500+280%
Original headlightsBosch H4 for Mercedes W126$800–$1,500+190%
Emblems and nameplatesChrome emblem Porsche 911 (1970s)$300–$1,200+350%
Transmissions5-speed manual transmission Getrag 240 for BMW M3 E30$3,500–$7,000+410%
Interior detailsNardi steering wheel for Lancia Delta Integrale$600–$1,800+220%

Where to look for such details? On specialized auctions (for example, Bring a Trailer in the USA or Mobile.de in Europe), in collector groups on Facebook and also on disassembly of old cars. The main rule: buy only parts with original catalog numbers and documentation.

💡

Before purchasing a spare part, check it in the database ETIS (for European cars) or JDM Parts Database - this will help avoid fakes.

3. Vintage tools: why old keys are more expensive than new ones

It seems like a paradox, but instruments from the mid-20th century are often more expensive than their modern counterparts. Reasons:

  1. Steel quality: in the 1950s-1970s, tools were made from alloy steel with a high content of chromium and vanadium (for example, keys Snap-on or Hazet of that period do not bend even under heavy loads).
  2. Design: Many vintage tools had ergonomics that modern brands do not replicate (e.g. hammer handles Plomb or screwdrivers Wera 1960s).
  3. Collectible value: complete tool sets (e.g. Kraftform in original cases) are sold at auction for $2,000–$5,000.

The most popular categories:

  • 🔧 Socket heads Hazet (Germany, 1960-1980s) - prices start at $50 per piece.
  • 🔨 Hammers Plomb (France) or Vaughan (USA) - collectors pay up to $300 per copy.
  • 🔩 Micrometers Mitutoyo or Brown & Sharpe (before 1980) - from $200 per working copy.

Where to buy? On eBay (filter by "vintage tools"), in antique shops in Europe (especially Germany and Sweden), as well as on Japanese auctions Yahoo! Auctions, where they often sell tools from closed factories.

How to distinguish original Hazet from a fake?

Original Hazet keys from before 1980 have:

1) Logo with a “crown” above the letter “H”

2) Marking "Germany" (not "Made in Germany")

3) Serial number on the back

4) Chrome plating without chipping (even after 50 years)

Counterfeits usually have dull metal and fuzzy engraving.

4. Unique license plates: how to make money on “beautiful” license plates

The market for personalized license plates is growing at 18% per year, with some combinations selling for hundreds of thousands of dollars. For example, in 2023 the number F 1 (UK) left the auction for £16 million ($20 million). But even ordinary “beautiful” numbers can be profitable.

What is valued on the market:

  • 🅰️ Single letter numbers: in Russia numbers of the type A 001 AA (Moscow) cost from 500k rubles, in Ukraine AA 00001 - from $10k.
  • 🔢 Repeating numbers: XXX 777 XX or AAA 111 AA — their price increases by 10-15% annually.
  • 💎 Gold/silver numbers: UAE number 1 (one character) sold for $14 million, and in China two-digit numbers cost from $50k.

How to earn:

  1. Buy license plates at traffic police auctions (in Russia) or local analogues (for example, DVLA in the UK).
  2. Look for numbers with history: for example, those that belonged to celebrities (no. MMM 777 Mikhail Prokhorov was sold for 1.5 million rubles).
  3. Invest in rooms new regions: when a new series is opened (for example, 126 RUS for Crimea), first numbers (AAA 001) can be bought cheaply and sold after 5 years for 10 times more expensive.
⚠️ Attention: In some countries (for example, Germany) the sale of license plates is prohibited by law. In Russia, only license plates are legally sold through traffic police auctions—buying "from hand" can be considered fraud.

5. Original documentation and manuals: why papers are more expensive than cars

It seems incredible, but original operating instructions, service manuals or even advertising brochures can cost more than the car itself. For example:

  • 📄 Original spare parts catalog for Porsche 911 (1965) - $1,200–$2,500.
  • 📖 Repair instructions Ferrari 250 GTO (1962) - $15,000+ (if signed by engineer).
  • 🎫 Promotional poster Ford Mustang (1964) - $300-$1,000 depending on condition.

Why is this in demand? Collectors and restorers pay big money for accurate information, especially for rare models. For example, without the original manual it is impossible to properly restore the injection system Bosch K-Jetronic on Mercedes 450 SEL 6.9.

Where to look:

  • Auctions eBay (filter "vintage car manuals").
  • Specialty stores, e.g. The Motor Bookstore (UK) or Buchhandlung König (Germany).
  • Flea markets in countries where cars were produced (for example, in Italy you often come across manuals for Alfa Romeo and Lancia).
💡

The most valuable documents are those that contain unique technical data (for example, wiring diagrams for limited editions) or have autographs of designers (eg Giorgetto Giugiaro).

6. Fuel and oils: why old cans become a rarity

This is one of the most unexpected categories, but the demand for original oils, additives and even gasoline of the past decades is growing. Reasons:

  • 🛢️ Collectors buy canisters with logos of legendary brands (for example, Castrol GTX 1970s or Mobil 1 first batches).
  • 🔧 Restorers are looking for original lubricants for engines that require specific oils (for example, SAE 30 for Volkswagen Beetle air cooling).
  • 💰 Investors buy whole batches of old oils in original packaging (for example, a box Shell Rotella 1960s can cost $500+).

Price examples:

ItemYearPrice (2026)
Canister Castrol GTX (1 liter, unopened)1975$80–$150
Box Mobil 1 (12 liter cans)1980$400–$800
Can Shell Racing (5 liters, with pump)1960$200–$400
Can of additive STP (original)1970$50–$120

Where to sell? At auctions Catawiki (section "Automobilia"), in collector groups on Facebook or through specialized stores such as Petrolicious Shop.

1. Check the integrity of the packaging (there are no signs of tampering)

2. Make sure that the label is original (compare with photos from catalogs)

3. Look for shipments with documents (invoices, certificates)

4. Avoid canisters with sediment or cloudiness (this reduces the value)-->

7. Car watches and accessories: small things with big profits

Not only cars and spare parts are becoming more expensive - even small accessories can become a source of income. For example:

  • ⌚ Clock Heuer Monaco (the ones worn by Steve McQueen in the movie Le Mans) - from $2k in 2010 to $20k+ in 2026.
  • 🕶️ Sunglasses Ray-Ban Aviator (original 1970s) - $200 to $1,000 per pair.
  • 🎧 Radios Blaupunkt (1980s) - working copies sell for $300–$800.
  • 🧤 Driving gloves Porsche Design (1990s) - $100–$300 per pair.

Where to look:

  • Vintage fairs (eg. Brick Lane Market in London).
  • Stores militaria (military and automotive accessories are often sold together).
  • Auctions LiveAuctioneers (filter "automotive memorabilia").

Tip: pay attention to accessories with automaker logos (for example, lighters BMW Motorsport or jackets Ferrari Scuderia) - they grow in price faster than generic brands.

FAQ: Answers to frequently asked questions about investing in rare items

🔍 How to check the authenticity of a rare spare part?

1. Check catalog number with the manufacturer's database (for example, ETKA for Volkswagen Group or EPC for Mercedes).

2. Check material and processing: Original parts from the 1980s are often hand polished, modern fakes are often stamped.

3. Order examination at specialized clubs (for example, Porsche Club of America or BMW CCCA).

💸 How much do you need to invest to start making money on collectible cars?

Minimum budget - from $5,000. For this amount you can buy:

  • 🚗 JDM-auto entry level (eg Nissan Silvia S13 in good condition).
  • 🔧 A set of rare spare parts (for example, carburetors Solex for Citroen 2CV).
  • 📄 A collection of original manuals (for example, a complete set for Volvo 240).

The optimal budget for a stable income is $20,000+. This will allow you to diversify your portfolio (for example, buy a car + spare parts + accessories).

⏳ After how many years does a thing start to become more expensive?

It depends on the category:

  • Cars: minimum term - 20 years (for example, BMW M3 E46 prices are already rising). Peak growth is 30-50 years.
  • Spare parts: rare parts begin to rise in price 15-20 years after the model is discontinued.
  • Documentation: manuals become in demand after 25-30 years (when the last car of this model breaks down).
  • Accessories: Vintage watches or glasses begin to appreciate in value after 10-15 years (eg. Casio G-Shock 1990s are already becoming more expensive).
📈 How to track rising prices for rare items?

Use these resources:

  • Auction archives: Bring a Trailer (for cars), Catawiki (for spare parts and accessories).
  • Indexes: HAGI Top Index (tracks prices for classic cars), Classic Car Market Review.
  • Forums: PistonHeads (UK), Jalopnik (USA), Drive2 (Runet).
  • Social networks: Facebook groups ("Classic Car Investment") or Telegram channels ("Avtoinvest").

Tip: Maintain your own table in Google Sheets, where you record prices for the lots you are interested in once a quarter.

🚨 What things are better NOT to buy for investment?

Avoid these categories:

  • 🚘 Mass models (for example, VAZ 2107 or Ford Focus first generation) - there are too many of them for them to become a rarity.
  • 🔧 Non-original spare parts (for example, Chinese replica carburetors Weber) - they have no collection value.
  • 📄 Photocopies of documents — only originals with the manufacturer’s seal have value.
  • 🛒 Things without a story (e.g. license plate without proof of legal ownership).

Rule: if the item can be easily found on Avito or OLX in unlimited quantities, it is unlikely to rise in price.
