Just traded my car in against a 56 plate Fabia Sport and I'm amazed at the price I got for it. It was a 2000 (W Reg) Corsa 1.0 Envoy, 5 door model with the most basic of basic specs, no power steering, cassette radio etc. The one thing good about it is it had a decent service history and had only done 45k. Book value only 550, I got 800 for it! I paid 900 for it 3 years ago. 100 quid depreciation in 3 years is fantastic. Chuffed!
