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.
Most 2020 diesel 8 Series examples are the 3.0‑litre straight‑six (e.g. 840d) paired with BMW's 8‑speed automatic; many were sold as the four‑door Gran Coupe rather than a traditional two‑door. As a modern diesel it has a Diesel Particulate Filter (DPF), EGR and an AdBlue system—these need proper motorway use or they can give faults. The automatic gearbox and adaptive suspension are smooth but expensive to repair if neglected, so look for service records specific to those items.
- DPF/EGR history and regeneration logs—look for frequent short‑trip faults or stored DPF/AdBlue warnings
- Automatic gearbox behaviour and service history (smooth shifts, no slipping, confirm gearbox oil change interval was followed)
- Turbocharger and oil leaks (signs of smoke on booting off throttle or visible oil around turbo lines)
- Adaptive/air suspension operation (rising/sinking, compressor noise or fault messages) and condition of dampers
- High‑cost electronics/options (camera, central locking, infotainment) — check all functions and watch for persistent warning lights
Spanner’s our AI mechanic — always have a proper look at the car in person before buying.
