Stay away from this car, the problems sound to me like a lot of leaks in a lot of bad places. Low oil means that its either neglected or has been slowly leaking into places oil shouldn't be getting. Good performance tires for that car will run you 250-300 Dollars, whats that, 150 pounds, or more. I think the person who owns it either had no idea what they were doing with a high performance car, or beat on it hard and realizes its got some issues and is trying to unload it!
