Jim, i sold my Sapphire Cosworth, on PF, for £7500 cash, within 24hrs of advertising her. The fella knew what he wanted to buy, had the cash and has bought himself a fabulous reliable and fast car that i hope he will enjoy and look after if not improve.

Good cars are hard to find and enthusiaists are out there that wish to buy them already done up when they can find one, and yours is a seriously good car with a great NMS engine and power conversion. I would personally give selling her a try and see how you get on before you break her as it would be a shame to see her broken up for spares.
