Byas,
Looks like a nice car as far as Bav's go. I don't care for black and I'm not certain if it was an original factory color (not that you care) for Bavarias.
Chris: I don't see anything off with the center front bumper, do you?
It appears to have an electric fuel pump as seen in the trunk shot. It may mean the head has been replaced with a later one without a provision for the mechanical pump. This is a positive, meaning you have an updated head, less prone to cracking.
Something happened (rust?) on the rear shock towers that required welding as pointed out here. Where that swath of seam sealer/welding is on the wheel wells there normally is a row of spot welds (you can see some) for a strengthening plate piece under the wheel well. Something also happened in the left rear, next to the brace where you can see a vertical swath of welding/seam sealer.
This is what wheel wells/shock towers look like from the factory: no sloppy welds and seal sealer. Dealer is just ignorant of this. You're on your own, they are just trying to sell a car. (The car in this pic has 1974 and later strengthening braces yours should not have):
The exhaust pipe placement is a mystery as all Bavarias had it to the extreme right as seen here:
Or as in the late years 3.0 Si's, to the left of the license plate:
All of this doesn't mean it's not a good car, I just would want to know as much as I can about its past and all these clues tell you part of the story.
If I were buying, I'd like to see some undercarriage shots. As well, the graininess of photos bothers the heck out of me. They look like 70's Kodacolor shots, inexcusable in the digital age.
There have been 2 or 3 nicer, IMO, Bav's posted here. One was a beige one from Minnesota and a couple others I forget where they were from. Maybe I just can't get past the (bad) black...
