I just purchased a 2001 740i with 137000 from a reputable dealer in Pittsburgh. I found a Indy in my area that says he works on BMW and closer to my home. I asked him if I could bring the car by to have him check it over. I trust the dealer I bought it from...but I wanted another opinion. When I called to schedule an appointment, he asked me a really odd question..." When was the last time the timing belt was changed" :eeps:I thought the E38 had a timing chain and it should be check out but not changed periodically. Am I right or should I be a little worried about this Independant Shop....
