Agreed. When I had my e30 running,i went to the e36 manual and to this website for support.I used the e30 manual for all body interior and electrical uses as well as torque specs for things such as differentials and exhaust diagrams.
Honestly, check this site and ask people in their specific niche. If you cant find it here, it is probably online but from experience, always post on this site first.
I have applied to many sites for my Audi a4 and they all suck.. Everyone goes to a mechanic and no one is a true gear head without being gay about how their car is functioning.
Almost everyone on this forum can help you and can help with any specific question. No question is stupid to ask here because some people have trouble with these cars.Good luck with your e30 and if anything happens to it mechanically, ask here
Good luck with your e30!!!
