My rear passenger side floor pan rusted through.
My emergency brake cable broke.
My power steering pump doesn't work.
The alternator was seized.
Rust on the fenders, roof, and in the trunk.
The seals in the trunk and sunroof leak.
Torn cv boot.
Well to begin with most of the problems with this car are age related, but other than that it's a pretty solid car mechanically.
It was in rough, but runnable shape when I bought it, but with a bit of work I managed to get it back on the road for a year without too serious of problems.
Basically its not on the road now due to it needing a new floor pan, Emergency brake cable, tire and mirror before it can pass Motor vehicle inspection, but those should be fixed soon without too much problems and it still runs like a top.
It handles pretty tight, gets torque around 3500 RPM and up and even with the non working power steering pump it still corners great.
I find that it's a great car despite the fact that its showing its age on the outside, but around here cars have shortened life spans due to potholes and road salt, but this car has held up pretty well and is still on the go.
Why would you dump money into a rustbucket?
Based on your description, it does not sound safe to drive, even with the floor replaced.
Unitized bodies that have started rusting out are bad news.
"RUST NEVER SLEEPS"!
Yeah, keep that bugger on the road! As long as there are parts to be found, roll on. Make sure you undercoat the underside well (after repairs)and you could be set to go!
