The air conditioning didn't work.
The cruise control didn't work properly.
The aerial was broken, so the radio didn't work properly. The tape player wore out.
The driver's door power window did not work properly.
The electric seat control was worn out.
The trunk could only be opened from the inside.
The speedometer did not work.
The bumper trim was badly chipped.
The car was generally starting to rust out.
This poor car had been damaged during a tornado, which could explain why so much did not work. That said, I really miss my Caddy (it was stolen), because even with all that was wrong with it, it still had the light handling, the quiet, smooth ride, and the understated elegance of a Caddy.
Wow, how long did you need to leave it running with all the windows down before somebody finally took it?
Have an '85 coupe myself and an '89 sedan planning to do the 4.5 engine swap to the coupe. If your car ran anything like my coupe does now, I'd like to know what the hell the thief was thinking.
