I would leatherique the interior and see what you end-up with. Leatherique is amazing stuff. You might find that color very rewarding. Some BMW enthusiast worship that interior.

If you are doing a full restoration, I would strip the interior and start over with new carpet and wrap the seats in new leather. If you are looking for a fun beater. I would stick with leatherique and save the money for maintenance repairs (RTABs, Suspension components, Cooling system components, FLuids, and gaskets) all of which are prone to wear and tear on the E36 M3.

Great car, Fun project. I have to admit, I'm envious. Looks like alot of fun. GL
