Just bought a 1990 E32. I am interested in where other E32 owners
have installed A/C units and what size? (I'm in NC) Any suggestions
would be helpful.
Congrats on your purchase! I can't help on the a/c question but someone here is bound to know something that will help. I've got an E32 very similar to yours as do a number of folks here.
You might try searching and see what you can find.
