Older= more problems, tierods, suspension, alternators, PS pumps, etc..
buy the newest car you can afford honestly if a 93 is .3 seconds faster than a 98 LSC who gives a crap, in real world "Street driving" that is hardly any difference. And honestly 95% of the cars on here are daily drivers and not track whores like some 87-93LX foxbody Mustang.
I prefer the 97-98 LSC myself. The older ones to ME look dated especailly the grill and front end headlights etc... not that I hate it, I just prefer the newer grill and headlamps.
