€25k for a 2nd hand car????? In the immortal words of Bill and Ted, "are you mental?"
But specifically with relation to this car. The car is expensive to maintain, though lovely to drive. If it's the turbo version, the turbos are quite likely to go after 4-5 years. This is a €3-5k replacement job. The lcd display on the dash will also disintegrate (visually) after same period of time also. The ecu in the car is enormously unreliable and can severly impact fuel efficiency if it goes wrong, and can only be fixed by replacing - also a repair job costing in the thousands.
Bear in mind that garages are offering €11-12k on trade-in for 01 versions of the same car, 75k mileage. . Just to show you how ridiculously expensive €25k is for a car 2 years older.
