Turbo Seized (twice) 125000, 150000
Air Conditioner system failed (twice) 122000, 148000
Head Gasket failed 150000
After new head gasket and turbo, timing belt broke
Each time the turbo broke, it was over $900 to fix. When the AC broke it cost $1000 the first time (didn't do that again!)
Plagued with lots of rattles and random strangeness; check engine light would come on at random intervals and go off the same way, windshield wipers would wipe whenever they felt like it, dash lights flickered.
I will say that I did love driving it as it was terribly fast (for what it was), and I liked the way it looked. However, the cost of repairs was just totally unreasonable.
I suppose it was a decent car, I just didn't know when to get rid of it.
My 1990 Sunbird GT gave me 310,000 miles of flawless performance. I just bought a new sunfire. I hope it's half the car my old sunbird was.
My friend has a 89 Sunbird GT 5spd that is running great. The body has held up well, but the engine has had lots of work done on it. The best part... it has over 500,000km and looks like it has 100,000km. And it still goes like stink!
