I am the happy owner of a 1992 735i, 50K miles in showroom condition. I've had several offers to buy the car lately and am wondering if this is due to the color combination. The car is brilliant red with a very light grey leather. I've never seen another brilliant red 7 series and was wondering how I could determine if this is a fairly limited option. Is there a web site that documents production runs etc? Thanks for any direction.
