my mint 50,000 mile car suffered....
blown head gasket
front crank shaft oil seal failure
auto box shudder
front ball joint noise
weeping rad (improperly made at factory, not corrosion)
transmission fluid leak
brake light failure
intermittent indicator stalk problems
coolant temp sender failure
EGR valve failure
02 sensor failure
drivers seat was starting to collapse
this was not good for a car I drove less than 25,000 miles in. my last real drive was at 40mph on the hard shoulder of the M6, because it wouldn't go any faster, and it still holds the record for most times on a flatbed (5 times)
in fact, it was on a flat bed more times than every other car i've ever owned combined.
if you must have one, get the V8, the V6 is terrible. the stock V8 is pretty damned lethargic though, but it does seem to basically hold together..
Interior quality is a little better than a 4th gen, but then what isn't? (except maybe a Le Barron)
late 90's early 00's were a real black hole for yanks, they just seemed to go to hell in a hand cart, only just getting back in stride recently.
