A €2,383 spread between the 25th and 75th percentile. Spec, service history, and colour drive significant price variation, research carefully.
2
Normal market turnover at 16 days average. You have time to be selective, but don't sit on a great deal.
3
Mileage is a major price driver, low-mileage examples cost 33% more on average. Worth paying if you plan to keep the car long-term.
