Engine-wise, the only real problem I had with it was valve guides wearing out. It had new heads on it under warranty when I got it, and about 80,000km later I had to have them rebuilt again due to oil consumption - which damaged the catalytic converter.
The car was hard on universal joint rubbers - replaced at least 6 times.
I replaced the brakes 3 or 4 times.
The transmission went bad at about 200,000km. It was the 3 speed, and the differential bearings went bad, putting filings through the whole system. I was lucky and got a good low mileage transmission cheap.
The AC condenser leaked. I replaced it.
The AC evaporator leaked. I replaced it.
An AC hose leaked. I replaced it.
The AC compressor failed.
The heater motor quit - I put in new brushes and it was fine.
The air adjustable suspension quit. The compressor failed so I took it off and put in CargoCoil springs.
Water pump went bad.
The water tube from the pump to the rad that goes under the intake manifikd went bad - miserable to replace.
Alternator quit. New brushes and bearings fixed it first time. Went bad again several years later and I put on a used one.
The engine pulley came off and damaged the crank snout. I repaired it with LocTite shaft and bearing mount.
