UPDATE... I advertised the car again as a 'winter project' and explained exactly what happened. I had my first viewer within 20 mins of the ad going live and the car is now sold. Just waiting on it being picked up. Was sold to a gentleman who owns a repair shop and also happens to have a damaged boxster with a perfectly good engine...
By my reckoning I've lost around £4,000 on the car since I bought it but if I had bought a brand new Ford Focus I probably would have lost the same amount... At least this way I had the thrill of owning a Porsche... Thanks for all the help over the last few months and happy motoring
