On the one hand, I'd be very comfortable with the car in this state. OTH, I've been working with these cars for the better part of three decades. Your joy will be a direct function of how much time you'd like to spend bonding with this machine. If you can put in the time, it will reward you with hundreds of thousands of miles of reliable fun.

The most serious of the problems you've described is the rubber...other than maybe the windshield, pretty much all of it is unique to the CD, and can be hard to find.

The dash wood has peculiar construction...it's wood laminated onto metal, and adhered to the dash with a foam/glue strip. when the glue dries out, they pop off and repairing them the right way...removing the entire piece, removing the old glue strip and reinstalling...is tedious and messy work. But now those bits are ruined. So you'll have to price out new pieces.

It certainly needs a wheel alignment, and may need new springs.

Uncracked dashes may be hard to find, but you can get a Coverlay, which is a plastic cap that comes in matching colors.

Rear window hardware is unique to the CD. Hopefully a spot of grease will do it. But if it can't be fixed, you'll have to hunt up a new regulator.

The fuel gauge is likely to be the sender, but it could also be the gauge. It should be an afternoon's finagle either way.

Be aware that although these are mechanically identical to 300D's, virtually all the body parts from the firewall back are unique. This is true of the seats, so make sure there are no broken springs in the bottoms.
