Man, you mean I have to pick just one? Okay, I guess I could just lump all the GM FWD V6 shitboxes I've owned together- in the friggin crusher, preferably. The first was an Olds Cutlass Ciera I got from the local used car dealer (MISTAKE) after my '70 Dart was T-boned. Great car, right? Working seatbelts! FM radio! A functioning heater! So much luxury! Effin tranny on that car exploded (no, not a metaphor) after about 3 weeks. A month after that, a camshaft **** the bed.. I told the towtruck guy where the dealer lot was and never saw it again. Next experience along these lines was an '82 Buick Century. Threw a rod after a month. Should have learned my lesson right there, but these cars were everywhere, and cheap, so I've owned like 8 of the damn things. At least the first two GM products did me the honor of having massive mechanical failures- pretty much every one after that did the "runs great/dies for no reason/won't start/starts right up an hour,day,week later/runs great/dies for no reason etc" weird untraceable electrical fault crap. In my family this is known as "Buick's Disease". Maybe if the ECU wasn't so busy regulating the power-assisted 3-way memory digital cupholders and crap like that, GM could design a car that would actually run.
