Replace both front door latches (twice)
Wore out the turn signal switch (twice)
Replace the alternator at 275,000 miles.
AC quit a couple of years ago.
Brake proportional valve stopped sending fluid to the rear calipers.
300,000 miles on a GM! WOW. Other than the items above this car has been great. Still has the original battery and original exhaust! Only consumed 3 sets of Goodyear Eagle GA tires.
I just bought a 1994 Cutlass Supreme today
04-06-07 with 79,000 actual miles.
Sounds like it might go a long time.
