Hi, always admired these cars and im finally looking to get one in the next couple of weeks? Im not very mechanically minded and could use some advice. What should i be looking out for when shopping for one? Dont go over any sort of mileage? Common faults etc? Any help would be great. Also, where should i shop for one? Ive just been looking on Autotrader at the moment. Thanks guys.
