Our take on the BMW 4 Series
A 2023 BMW 4 Series typically advertises at €46,950 and a 2018 one at €22,000, so it loses roughly 14% of its value a year at that age, faster than most cars. Most for sale are diesels (72%), which suit longer, regular drives; for mostly short trips a petrol is the safer buy. At the NCT, the 2015–2018 cars do better than other cars the same year. The 2.0 diesel is the most common engine (70% of those with a known engine), and it usually lasts around 280k km.

Engines and how long they last
| Engine | Usually lasts | Motor tax / year | For sale |
|---|---|---|---|
| 2.0 Diesel | ~280k km | ~€270 | 132 |
| 2.0 Petrol | ~280k km | ~€600 | 30 |
| 3.0 Diesel | ~400k km | ~€790 | 20 |
| 2.0 Hybrid | ~280k km | ~€270 | 7 |
2.0 Diesel: usual problem: timing chain at the back of the engine: very dear to replace.
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
