im about to go buy a 2003 3.8 v6 mustang with 67k miles on it, but i had some concerns. When i tried to start it it took about 3 seconds or so before it really turned over and started idleing(no sputtering sounds as far as i remember). But Should i be concered that the fuel pump, alternator, or starter is about to go out. Or just write it off as a problem caused by sitting on the lot for a week?
