Help! I am considering buying a "88 735i. It is silver w/ black interior. Exterior is literally perfect but the interior is worn but is readily fixable. This car has very high mileage ie. 295K. Local BMW shop has serviced this car since new and removed the head last summer and reworked it. They say it is in pristine condition. Private owner is selling...he wants 6K. Any ideas , opinions etc. I currently own a '87 635 L6. I'm a believer but I want some advice from 735 owners. TIA
