Spanner can help turn your car details into an advert.
Could suit you if…
- 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 room for several children or extra passengers: the seat count is not recorded. Confirm this exact version's seats and child-seat fit; do not assume from the model name.
- 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 G20-generation 3 Series saloon with a diesel engine and BMW's 8-speed automatic gearbox — common engines are the 318d/320d/330d diesels. Diesel BMWs have DPF and EGR systems and many models use AdBlue (SCR) so look for evidence of regular long runs and AdBlue top-ups; the ZF auto is smooth but benefits from a documented transmission service.
- DPF condition and regeneration history (short-run town use can clog DPF)
- AdBlue system — tank level, dosing failures or warning lights
- Automatic gearbox shift quality and service record (hesitation, hard shifts or fluid-change history)
- Turbocharger for shaft play and any smoke on start/acceleration
- Suspension/steering for knocks or uneven tyre wear (rear subframe area for corrosion on Irish salted roads)
