When it comes to German buses with index "7", many people immediately think of legendary models Mercedes-Benz O307, MAN Lion’s City or Setra S 417. But in fact, behind this figure lies an entire era: from urban workhorses to luxury tourist liners. German manufacturers traditionally use digital 7 to designate certain series or modifications, and understanding this diversity can be difficult.
In this article we will analyze in detail which buses are hidden under the index "7", how they differ from other series, and what to look for when buying a used copy. You will learn about technical nuances, typical problems, and even how to determine the original equipment using the VIN code. And if you plan to use a bus for commercial transportation, you will find a comparison of fuel and maintenance costs for different models.
Spoiler: not all buses with “seven” in their name are equally useful. For example, Mercedes-Benz O407 is famous for its reliability, but its repair costs 30% more than its analogues from MAN. A Setra S 417 HDH — this is a completely different story with a unique suspension and premium interior. But first things first.
Which German buses have the index "7"?
German manufacturers use digital "7" bus markings vary, but most often it indicates:
- Series or generation (for example, Mercedes-Benz O307 - third generation of city buses).
- Body length (in meters or conventional units, as in Setra S 417, where "417" denotes the 12 meter version).
- Engine type or environmental class (on some models MAN "7" may indicate compliance with the standard Euro-7, although this is rare).
The most famous models with the “seven”: Mercedes-Benz:
- O307 (1980–1992) - legendary city bus with a diesel engine OM407.
- O407 (1990–2001) - intercity version with improved sound insulation.
- Citaro K (O530K) - sometimes the designation appears in documents "C7" for the short version.
MAN:- Lion’s City 12 (A77) - a modern low-floor bus with a hybrid modification.
- R07 - a series of tourist buses from the 1990s.
Setra (part of the group Daimler):- S 417 GT-HD - flagship tourist liner with a 3-axle design.
- S 317 UL — urban version with increased passenger capacity.
Interesting fact: Neoplan (another German brand) there are also models with “seven”, for example, Neoplan N4016/7, but they are less common in Russia.
Specifications: comparison of key models
To understand which bus with the index "7" suits you, let’s compare them according to the main parameters:
| Model | Type | Engine | Power (hp) | Fuel consumption (l/100 km) | Passenger capacity |
|---|---|---|---|---|---|
| Mercedes O307 | Urban | OM407hA (diesel) |
210–240 | 32–35 | up to 100 |
| MAN Lion’s City A77 | Low-floor | D2066 LUH (Euro 6) |
280–360 | 28–30 | up to 120 |
| Setra S 417 GT-HD | Tourist | OM471 (V8, 15.9 l) |
510 | 25–28 | up to 56 |
| Neoplan N4016/7 | Intercity | D2866 (MAN) |
360 | 26–29 | up to 60 |
Please note:
- Setra S 417 - the only one on this list with V8 engine, which ensures fast acceleration even with a full load. However, its maintenance costs 40% more expensive than MAN Lion’s City.
- Mercedes O307 - the most "voracious", but its advantage is indestructible mechanics. Many copies pass over 1.5 million km without capital.
- MAN A77 - leader in efficiency among city buses thanks to the system EfficientHybrid.
Critical detail: y Setra S 417 Before the 2015 model year, there is often a problem with frame corrosion in the rear axle mounting area. Check this when purchasing!
How to determine the original equipment by VIN code?
When buying a used German bus with the index "7" check first VIN code. It will reveal not only the year of manufacture, but also original equipment, which is critical for cost estimation.
Where to look for VIN:
- On the plate under the windshield (driver's side).
- In the vehicle passport (PTS).
- On the frame of the bus (usually on the right, under the cabin).
VIN decoding for German buses:
1. First 3 characters (WMI) — manufacturer identifier:
- WDB — Mercedes-Benz.
- WMA or WMX — MAN.
- WDS — Setra.
2. 4–8 characters (VDS) — description of the model. For example:
- O307 at Mercedes will be encoded as 307.
- A77 at MAN Lion’s City - how A77.
3. 9 character — check digit (checked using an algorithm).
4. 10 character - year of manufacture (for example, L = 2020, M = 2021).
5. 11–17 characters - serial number.
Example: VIN WDB6700307A123456 stands for:
- WDB — Mercedes-Benz.
- 6700307 - model O307 (city bus).
- A — 2010.
- 123456 - serial number.
If in the VIN code of the bus Setra there is a letter H (for example, S 417 HDH), this means high roof (High Deck), which is important for tourist transportation.
⚠️ Attention: If the year of manufacture is indicated in the PTS 2010, and by VIN code - 2008, this may indicate number interruption or an error in the documents. Check your history through services like Autocode or CarVertical.
Typical problems and weaknesses of buses with index "7"
Even a German assembly does not guarantee the absence of “diseases”. Here's what most often breaks down in buses with the "seven":
Mercedes-Benz O307/O407:- Corrosion of side members - especially in the area where the footrests are attached.
- Leaks in power steering (repairs cost 15–20 thousand rubles.).
- Turbine wear after 400–500 thousand km (replacement - 80–120 thousand rubles.).
MAN Lion’s City A77:- Air suspension problems (the rear axle often “sags”).
- Electronics — errors on the CAN bus due to contact oxidation.
- Engine D2066 sensitive to fuel quality (when filling with diesel fuel below Euro 5 the injectors clog quickly).
- Cracks in the frame (especially for models before 2010).
- Automatic transmission overheating (oil change required every 60 thousand km, and not 100, as they say in the manual).
- Expensive spare parts: for example, the front axle is standing 250–300 thousand rubles. (against 150 thousand at MAN).
⚠️ Attention: If you purchase Setra S 417 for intercity transport, be sure to check conditioner condition. Its repair (refueling + compressor replacement) costs 180–220 thousand rubles. - this is 10–15% from the cost of the bus itself!

Cost of ownership: which is cheaper to operate?
Let's consider costs per 100,000 km for three popular models (data for 2026):
| Model | Fuel (diesel) | Maintenance (oil, filters) | Repair (medium) | Insurance (CASCO) | Total |
|----------------------|------------------|---------------------|-------------------|-------------------|------------------|
| Mercedes O307 | RUB 1,050,000 | 180,000 rub. | 350,000 rub. | 220,000 rub. | RUB 1,800,000 |
| MAN Lion’s City | 900,000 rub. | 200,000 rub. | 280,000 rub. | 250,000 rub. | RUB 1,630,000 |
| Setra S 417 | 850,000 rub. | 250,000 rub. | 500,000 rub. | 300,000 rub. | RUB 1,900,000 |
Conclusions:
- MAN Lion’s City - the most economical to operate, but less comfortable for long trips.
- Mercedes O307 - the gold standard of reliability, but gluttonous and requires frequent replacement of consumables.
- Setra S 417 - expensive to maintain, but justifies itself in the premium segment (for example, for VIP transportation).
Tip: If you plan to use the bus for city routes, take it MAN. For intercity flights — Setra (despite the price, it pays for itself in 3–4 years due to passenger comfort). Mercedes O307 - optimal for secondary market, if needed cheap workhorse.
Saving on fuel MAN Lion’s City (15–20% lower than Mercedes O307) offsets higher insurance and maintenance costs.
Where to buy spare parts and how to save money?
Original spare parts for German buses with index "7" are expensive, but there are ways to cut costs:
1. Alternative manufacturers:
- For Mercedes O307 fit parts from Bosch (injectors), ZF (gearboxes) and Knorr-Bremse (brake system).
- For MAN Lion’s City — Sachs (shock absorbers), Wabco (pneumatics).
- For Setra S 417 — Voith (torque converters), Hella (optics).
2. Where to look:
- Official dealers: expensive, but 1-2 year warranty. For example, spare parts for Setra supplies in Russia "Daimler KamAZ Rus" (prices for 20–30% above market prices).
- Specialty stores:
- "Bus spare parts" (Moscow, St. Petersburg) - discounts up to 15% for wholesale purchases.
- "Herman Auto" (Ekaterinburg) - specialize in MAN and Mercedes.
- Showdown:
- "Avtorazbor 24" (Moscow region) - often there are contract engines OM407 for 150–200 thousand rubles. (a new one costs 500+ thousand).
- "BusParts" (Germany) - delivery takes 2-3 weeks, but prices are lower by 40–50%.
3. How to save on repairs:
- Do-it-yourself oil change in automatic transmission (saving 15–20 thousand rubles. at a time).
- Buying consumables in bulk (for example, filters Mann for MAN Lion’s City cheaper by 30%, if you take a pack of 10 pieces).
- Using analogues for non-critical parts (for example, brake pads from Textar instead of the original ones).
How to distinguish an original spare part from a fake?
Original parts for Mercedes and Setra have:
1. Laser engraving with serial number (checked through the service Mercedes-Benz Parts Verification).
2. Hologram on the packaging (at MAN - blue color Setra - silver).
3. Marking "Daimler AG" or "MAN Truck & Bus" (on metal parts it is stamped, not glued).
Legal nuances: registration and operation in Russia
Buying a German bus with an index "7" associated with a number of bureaucratic issues:
1. Customs clearance:
- Buses are older 7 years cleared through customs reduced rate (5–10% of the cost).
- For Setra S 417 (if he is under 5 years old) will be required certificate of conformity (cost - 50–80 thousand rubles.).
2. Refurbishment:
- If the bus tourist (Setra, Neoplan), for use in city routes you need:
- Install turnstiles and CCTV cameras.
- Get permission from the traffic police to change category (from M3 on M2).
- Refurbishment cost: 200–400 thousand rubles. (depending on the region).
3. Insurance:
- OSAGO for buses with more than 16 places worth it 40–60 thousand rubles. per year.
- CASCO - from 150 thousand rubles. (for Mercedes O307) to 350 thousand rubles. (for Setra S 417).
⚠️ Attention: If the bus over 10 years old, some insurance companies (for example, "Ingosstrakh") refuse to issue CASCO without preliminary technical inspection with diagnostic card. Cost of inspection - 8–12 thousand rubles.
4. Technical inspection:
- Bus categories M2/M3 undergo maintenance every 6 months (unlike cars, where once every 2 years).
- Average maintenance cost: 5–7 thousand rubles. (excluding repairs).
FAQ: Frequently asked questions about German buses with index "7"
Is it possible to put on Mercedes O307 gas equipment?
Technically yes, but this is unprofitable:
- Installation cost HBO-4 — 180–220 thousand rubles..
- Fuel savings - 30–40%, but engine life OM407 is reduced by 20–30% due to increased combustion temperature.
- Payback - 5–7 years (with mileage 50 thousand km/year).
- Conclusion: is it better to stay on diesel or consider MAN Lion’s City with factory hybrid.
Which bus with "seven" is the most reliable for Siberia?
Suitable for extreme conditions:
- Mercedes O307 - thanks simple mechanics and resistance to low temperatures (starts at -30°C without heating).
- MAN Lion’s City (with D2066 engine) - has Webasto preheater as standard.
- Not recommended: Setra S 417 — its electronics are sensitive to frost (frequent malfunctions MUX buses).
Tip: before winter, be sure to check:
- Condition batteries (capacity not less than 180 Ah).
- Work interior heater (in Mercedes O307 breaks often Eberspächer).
How much does a contract engine cost? Setra S 417?
Prices for 2026:
- Engine OM471 (V8, 15.9 l) — 600–800 thousand rubles. (new), 300–400 thousand rubles. (contract with mileage up to 300 thousand km).
- Automatic transmission Voith DIWA — 450–600 thousand rubles. (new), 200–250 thousand rubles. (used).
- Important: When purchasing a contract engine, check:
- Availability guarantees (minimum 6 months).
- Condition turbines (a common problem is oil burn after 400 thousand km).
- Compression in the cylinders (normal - not lower than 30 bar).
Is it possible to remake MAN Lion’s City in a camper?
Yes, but this expensive and difficult:
- Legally: Re-registration from M3 (passenger) in N3 (cargo with residential module). Cost - 100–150 thousand rubles. (lawyer services + examination).
- Technically:
- Seat removal and installation furniture will cost 300–500 thousand rubles..
- Needs to be strengthened floor (in buses it is not designed for static loads).
- Problem with heating — a standard stove will not cope with heating the interior in winter.
- Alternative: buy ex tourist Setra S 417 - he already has wall insulation and powerful heating system.
What kind of oil to put in Mercedes O307?
Manufacturer's recommendations:
- Engine OM407:
- Summer: MB 228.3 (for example, Mobil Delvac MX 15W-40).
- Winter: MB 228.1 (for example, Shell Rimula R4 L 10W-30).
- Replacement interval: 15,000 km (or once a year).
- Gearbox VOITH D851:
- Oil VOITH H55.6335.XX (analogue - Shell Spirax S4 GX 75W-90).
- Replace every 60,000 km.
- Important: never use universal oils (for example, 15W-40 for gasoline and diesel engines) - this reduces the turbine life by 30–40%.
