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 | ~€570 | 30 |
| 3.0 Diesel | ~400k km | ~€750 | 21 |
| 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.
