Hi Jeremy,
Given that it's an early car, #37 produced, has a mild SB Ford motor without Webers, a Getrag transmission rather than a ZF and no stated mileage, the high side of the guide price probably represents the actual cost of building the car in 2003.
At todays prices an equivalent car is nearly double the money so I'd say it's a roaring bargain. It also falls in line with other early CAV GTs that have changed hands recently. There is little to no depreciation. Plus the SVA is done.
The colour appears to be Titanium Silver, darker than the Polar Silver, great looking in either case. Get out your cheque book mate.
Cheers
