Honestly, I cannot complain 220,000 miles plus and I still hit the highway without a second thought. My 733i is great! Recently the front passanger seat rear up/down power button stoped working. The seat is in the down postion and pressing the down button activates the motor. However, the up button gives no response. All other functions work. I tried switching the unit with the drivers seat unit, same response. Any ideas???
Also body wise what is different about the 1986 735i, as compared to my 84 733i. I can't put my hands on it.
