I’ve been toying with changing my tintop, I use wewantanycar.com as a general guide to values. Seen a car at my dealer, they’re asking 31k for it, 12 months old, 10k etc.. wewantanycar ‘s offer was £ 27,450. They offered £16450 for mine, dealer £15800. Got an email from webuyany car yesterday with revised offer for prospective purchase, £17,600 ! Due to ‘downturn in the automotive industry’. Buyer beware but there will be some real bargains out there soon........
