I can't find an allen wrench to remove my brake calipers anywhere. It is between 6 and 8 mm, but I can't even find a 7 to test. I have an '82 528e. Any ideas?
Also, what is the best/cheapest way to get more performance? I got my car for $800. It has bad paint and burns a lot of oil. It also has a 3-speed auto. Would it be better to work on this car, or look for a better one, like a 533 or 535?
