I really like them cars, to much power for front wheel drive though. Just wheelspin alot....
www.vpuk.com is a good site to go on, they have a section on what to look for when buying one but a couple of points are:
check top engine mount on them, check all the milage carefully because theres abit to do with the speedo cable that breaks sometimes, check the heated seats arent getting really hot because it was a recall job because the seats where burning, cant remember anything else atm but aslong as its got a full service history the milage isn't a problem.
