I am the owner of the 1971 2800 5-speed. I encourage you to check out the auction listing on Bring a Trailer, the auction finishes about 5:00PM Eastern on Tuesday.
I bought the car about five years ago after search for and visiting a lot of E9's over many years. I have always been very committed to BMW, ever since I bought my daily driver 2002Tii in 1973. When I found this car, I was stunned that it was a one owner, pretty much all original (with the exception of a BMW factory authorized repaint about a year or two after purchase) and it did not have traditional rust issues. It was a unicorn among E9's.
The undercoating pictured on the underside of the car is part of the Ziebart process which was applied when the car was new. There was some passenger side rocker repair about 5-6 years ago by a foreign cars shop in MN (likely POR 15), but other than that is is very solid. The car was purchased in Michigan, but has spent much of it's 51 years at a Florida home, stored at a repair shop on Minnesota, and in my garage in Tennessee.
Please visit the BAT auction site if you are interested in more original rather than redone BMW's. I have really enjoyed the original pigskin leather, carpets, door panels, dash, steering wheel, wheels, tool kit, etc. I have upgraded the car with a five-speed manual, Webers, and Pertronix ignition. It is still, however, a 1971 driving experience, with Coupe King springs, new bilsteins, and new control arms and tie rods. I love to try to make my old cars look and drive like that did when they were a couple years old, and as the say goes, "it can only be original once"! If this is also your preference in BMW's, check it out!
