I've had pretty good luck with my Intrepid. The only work done to my transmission was the coolant lines at 15K, which was obviously warrantee work, beyond that just transmission fluid flushes every 30K with Chrysler ATF+4. The engine needed an intake gasket at 90K, a new cooling fan at 145K this past summer, a new tie rod around 100K, freon (or whatever they use these days) recharge at 143K. Most of everything else has been regular maintenance. It has over 157K currently (3.5L 24 valve SOHC V6). My father's record holders are his 98 Taurus only needing new brakes regularly and a new wheel bearing at around 130K, his two 91 Dynasty's transmissions were starting to act up due to lack of maintenance at 135K (3.0 Vulcan 12valve OHV V6), plus a computer problem that made the engine refuse to start and needing a new starter plus burning oil (3.0L Mitsubishi powered). My mother's record is 127K with the oil pressure extremely low on her 91 Caravan (2.5L 2 valve SOHC) most of these miles were in town as it was about 10 years old. Her 02 Caravan has around 113K currently and counting, the problems have been suspension related and with the climate control and A/C needing a recharge. My dad's first two cars were Coronets that he put over 120K on both having the 318, the first one's engine locked up due to lack of use and maintenance as he was single and had the second one as a company car. He said both were pretty much trouble free.

The worst cars were had were the following:
Olds Ciera: transmission going out at 113K, with tons of sensor problems, ABS had to be worked on four times and still didn't work right, starter went out right after we took it off the lot, tire iron snapped, the windshield wipers would get stuck sometimes, the dash would shake if you drove it faster than 55mph, the suspension was pretty much shot, the engine didn't run right (and I never spent the money to figure out what was wrong with it), the gauges didn't work right, the alternator went out on it, the cup holder broke, the door handles broke on the inside of the door itself, etc.

Chevy Vega (my mothers that she had back in the 70s): Engine block cracked at 60K, she doesn't remember any other specific problems other than she said it was always giving her problems.

1982 Olds Cutlass Supreme 3.8L V6 I think: Carb had issues with stalling and getting it to restart was a task, the engine overheated a couple times from a blown water pump, it was really burning oil and not running well when we got rid of it at about 90K. It broke down a lot and I can't remember what went wrong with it. It was always having problems and leaving us strained.

1985 Chevrolet Celebrity 2.8L V6: timing chain snapped and it damaged the lifters, something went wrong with it and the axle broke, I can't remember anything else, we got rid of it before 100K if I remember correctly.

1979 Olds Cutlass (I don't remember which one it was): three wheel bearing failures, engine was burning oil, got rid of it with about 110K.

1976 Dodge Aspen slant six: carb problems and had to replace the torque converter. Got rid of it with about 90K.
