Welcome to the forum. Good luck with the hunt. They are rarely for sale with just 20 built, but prices are reasonable. The last one I saw was on Ebay a few years ago and it went for about 1000GBP (a blue or a white one,can't remember).
Cbeers guys, keep em peeled for me if you don't mind? Im genuinely interested, fancy one selling for a grand?, id happily pay 4 times that for the right car.... just my luck ill buy one then 3 will come along a week later, same happened with my Quantum
