My engine went at 246,000km.
My alternator died at about 100,000km.
My A/C is constantly giving me trouble. I had retrofitted from the old R12 and it just hasn't been anywhere near as cold.
I have had the front hubs replaced twice.
My cruise control hasn't worked for years.
When it was still new, I slid a bit in the snow and bumped the R front wheel against the curb - very lightly. But I put the rack out of alignment and bent the frame. The car has not handled the same since. It constantly pulls to the left. I can't count how many times it's been aligned- but to no avail.
The ECM has gone three times!!!
The fuel pump and heater core also needed replacing a few years ago.
Recently the power steering pump needed replacing.
When the car is working fine it's fun to drive. The acceleration is great and I don't mind the fuel economy. I just wish that GM had put a little more effort in the design of this thing. It really could have been a great car instead of just an okay car. I'll never buy another GM vehicle again, but it is my first and only car and in a weird sort of way I love it.
After all that, you'd probably have enough $$$ to buy a brand new or at least newer car!
Regarding your alignment problem, I had a similar problem with my '89 Z24, but it was fixed by a clever mechanic. I slid in the snow on a road in Colorado and slammed into the curb very hard on the passenger front side. It bent the control arm and one shop said $$$ to replace it. I went to another shop and the mechanic slightly notched the hole where adjustments were bolted down and after an alignment on the rack it drove like new, straight and true!
