Hello and congrats. My garage queen has 91K and the only semi-serious problem may be fixed. I added Bars Leak to the A/F as the heater core developed a leak. No leak for 3 months now; my fingers are still crossed. A couple of potential helps to you are:
There is a good guy (Kris) who fixes the very hard to find cruise control module for a very fair price and if you have the original Becker radio and your car is an early one, it DOES NOT come out with the regular tools. As I didn't want to break anything it took a couple of hours bending little tools as access is thru the cassette door. Also, there is another fellow who fixes these.
If I can help I am Ron at
rfpmoxie@charter.net.
Good luck!
