Hello All. This is my first post! I don;t have a BMW yet, but I have seen a 2002 E39 530i auto with 136,000 miles on the clock! Since i haven't a clue what they are like to own... what are they like for running costs MPG ( I don't thrash mt cars), repairs...( I read some where that the auto box is sealed and can't be repaired??) ..any likely faults? Thanks Dennis.!
