Oil leaks from mysterious places, seals will have to be replaced.
Display for heater, a/c display no longer lights up.
Tachometer seems to work when it wants to.
Leaking problem in front passenger footwell, I have no idea how the water is getting in.
Carburetor seems worn, will have to get it rebuilt.
Rear window defroster no longer functions.
Since I've had this car, I've only had ignition problems. Replaced starter, alternator and fuel pump. Haven't had any problems since.
Car is dead reliable, no matter how far or hard it is driven.
Handling is great, better than cars ten years its junior.
Regarding your leaky foot well, check if the wheel well has no holes. The plastic it is made up of eventually cracks and breaks. I had a 1986 Honda CRX that had the same problem. I found a palm sized hole on the upper left hand of the well. I filled it in, patched it up, and the problem was solved.
Hope this works.
