i'm pretty fortunate, i guess. TB every 100K, synthetic oil and filters every 10K, air filters, fuel filters etc... fan relay, blower motor, transmission mount...
Only major thing done has been clutch at 300K (needs a new transmission now, though), and I had a water pump fail a little while back.
It has its idiosyncrasies, and could use some interior and exterior work... glove box broken, annoying electrical issues, seat torn, bumps & scrapes on the outside... but she's a work horse and I've learned to deal with some of the annoyances.
She was a southern car - spent most of her life in Tennessee, so there's not really any rust/frame issues.
I will say that Firestone is kicking themselves for selling me a lifetime alignment
I'll bet they've aligned my car at least a dozen times. My mechanic seems to think there's no reason why it won't go to at least 600K - as far as the engine is concerned.
Other than that, this has been the best car ever! Hoping to get it to 600K and beyond!
