Actually ... I had to take the car in for an oil change and after talking to one of the secretaries, I got in touch with a used parts place in California, they sent me images of a used one, w/the rear roller blind for $85. I was so lucky, they only had one and it was in mint condition cuz the car was equipped with the blind. I got used rubber floor and trunk mats from the TI for $40 as well.
I have to say that this is one of the best aesthetic improvements I could have made to the interior ... I think I'm gonna save up for the armrest kit and chrome selector lever, I hate the small choice of automatic levers for BMW's ...
Thanks for all the help guys, especially Mr. Schlossman, this forum is amazing.
