Anyone here know how accurate these are (from http://www.parkers.co.ukwww.parkers.co.uk)? The Williams 3 I am going to look at tonight it a 96-N, 80,000, FSH and apparently in "A1" condition, but they want £6000 for it. Parkers value it at around £4900. Anyone know how realistic these prices are? I dont want to waste £1000 in the blink of an eye by buying an overpriced car.
