I want to buy a 1997 BMW 318i but I am a home mechanic and have no trouble working on my Ford’s or GM’s. I am wondering what the difference is and if i could work on my own BMW. I don’t want to do any major motor work just the basics. Example: Starter, Oil changes, Alternator, Tune up. What are some of the differences or obsticals i can come to expect. Is it an easy transition?
