Im sure that as long as you do the usual checks as with any new car accident damage, regular service, clean, personally i look a lot at who im buying it off of, nice area, keen driver, genuin reason etc. An for ?10000 you shold get a good one with low mileage!!Listen for smooth acceleration, put your foot down in first an second an make quick gear changes, an listen out for any hissin, or spinning noises, that'l be the diverter valve, ?100 to sort. Make sure turn off air con radio etc, an listen carefully. Oh an arrive early so the seller doesnt prepare with a run round the block to warm it up, u wanna get it on a cold start!! Hopefully that'l get u started there's plenty more experiance on here when it comes to the dubs!!

good luck
