I part ex'd my
Cupra in October and it was sat on another dealers forecourt until March. The price kept dropping. I think it probably sold for less than I got in part ex.
At the time Glass's and Parkers well overvalued the car, even after paying for the proper valuation from Glass's. What Car was closer to the mark.
The
problem with using the prices in Autotrader as a
guide are those are what people want for a car, not for what they eventually sell for. Some people are still dreaming with the prices they put cars up for.
I would image the most you would pay for a 57 reg is £12 - £13K from a main dealers forecourt.
£8600 is a little low, I got £13550 for mine and even at £500 a month depreciation should still be worth about £10K now. Plus mine was slightly older than yours.
There are also a lot of Cupras on the used market at the moment which can't
help...
