I'm sure this subject has been debated before but a search of the archives wasn't too helpful...
I was wondering if there is much difference in performance between (a) '82-84 633 (b) '85 635 and (c) '88-89 635 -which year did the hp/torque go up anyway?
I am not interested in an M car (been there, too expensive to maintain).
Finally, am I correct that the pre-1982 cars are best avoided?
Thanks,
Bill
