BMW on ebay
Beemer70,
I would suggest giving Munich Legends a call, to find out any more you can if you are interested in the car. Barney Halse and the guys at Munich Legends will remember the car and be honest about its appraisal.
It certainly looks good. The vinyl roof puts off some of our stateside cousins, but vinyl roofs were a 1970's British car fashion thing, and previous posts suggest they were put on new cars either as dealer options, or by BMW dealers before they left the showroom. We see more vinyl roofs on all UK 1970's cars, BMW included. Its a personal taste thing. My CSi had one when I bought it, so I put a new one on when restoring the car.
If you get the car, its up to you!
Good luck. Keep us all posted.
Just a thought............
