Spanner can help turn your car details into an advert.
Could suit you if…
- Your usual group fits within 5 seats, including the driver. Check passenger space and any child-seat fit in person.
- You regularly make longer journeys: diesel may fit that pattern better than a routine of mostly short trips. Compare actual running costs.
- You would prefer less gear changing in traffic: the recorded automatic transmission may suit. Try how this exact gearbox behaves on a test drive.
Think twice if…
- You need to carry more than 5 people together: the advert records 5 seats, including the driver.
- Most journeys are short school runs or local trips: check whether this diesel has a particulate filter and what longer runs its handbook requires.
- You need servicing to fit a tight budget: Spanner estimates higher maintenance costs for this type. Get quotes for the exact engine and gearbox before committing.
This is general guidance about this type of car and your needs — not an inspection or approval of this individual car.
This is the W223 S‑Class generation; common diesel variants are S350d or S400d paired with Mercedes’ 9‑speed auto and often a 48V mild‑hybrid system. Expect a diesel particulate filter (DPF) and AdBlue dosing system — both hate lots of short urban trips — and an air suspension/active ride system which gives great comfort but can be expensive if compressors or valves fail. The cabin electronics (MBUX, cameras, driver‑assist features) are feature‑rich but add repair cost and occasionally need dealer software updates.
- DPF and EGR condition – ask if the car has spent long periods on short trips and check for forced‑regeneration history or warning lights
- Air suspension operation and compressor noise/leaks (ride height symmetry front/rear and soft/sagging corners)
- Automatic gearbox service history (9G‑TRONIC oil/filter change) and for smooth, consistent gear changes
- AdBlue dosing system operation and tank level/lines for leaks or warning/limp‑home histories
- Electronics and driver‑assist checks – MBUX infotainment, camera/lidar sensors and adaptive cruise functions all working without errors
