That's Peter Salzman's car, the owner of Peter's Hobby Shop. I've seen it several times in person, it's not a show car but it is really nice and it's definitely Sahara. It might have a 3.5 in it but I'm not sure. It has very cool period staggered wheels that make the car.
Peter has worked on most of the old BMWs here in the Portland area, he knows his stuff. He's helped me through the years. When I removed my sunroof to polish the aluminum channels, he walked through the process (doing some of it himself) without charging me a dime.
It seems like a great price for such a nice, well sorted E3 with a little attitude.
