On third thought that rust could be fairly trivial. I'll bet there's a lot of it we can't see but the rear towers and trunk seem pretty solid. The front wings were a problem area too, IIRC. That rear facia is a common place for rust and not that significant until it gets down into the bumper mounts.
I grew up in a '74 2002 my Dad bought new. So many people asked us if it was a VW...silly. Great car, still my Dad's favorite.
Despite that, the 320i is like three times the car, and the e30 is even better. Rust was such a problem then...the '02 unfortunately rusted out quickly from a few fender benders despite (or because of) Ziebart-ing and we traded it in on an '81 VW Rabbit. They were both great cars, I'm always tempted by 2002's and mint green VWs.
I wonder at all the huge cars I see driving around these days...those wee little cars seemed just right at the time...and still seem that way to me today.
