I am looking to buy a used 1997 Ford Mustang, are there any major faults I should know of/ anythin particular i should watch out for? it has 117,000 kms on the clock and has no rust etc... engine looks to be nice and clean and well looked after and runs smoothly. the car didn't start the first time i tried it but it has been sat in -20 degree temperarures for a couple of weeks at least. is this omething i should worry about?
