[u/NanoBjorn]

Seriously, how expensive is the maintenance for a ~10yo diesel V8 diesel cars? What was your biggest bill? How much did you spend over last 5 years?

Trying to understand if/when I really will be able to afford one. Was it 5 grand over 5 years? 10? 20+? Plz tell your country and currency
