I've recently purchased a '98 BMW 520i and i'd like to be able to do some of my own servicing on it (such as oil changes/brake pads/discs etc) but the problem is that i dont really know anything about car maintenance. Does anybody know if you can do courses on such a thing or get some private tuition ? I dont want any qualifications in it or anything like that but i'd like to know what i was doing.
