I just bought brand new stainless steel brake lines and was having them professionally installed. The shop called and said the suspension is rusted through and he would not recommend repairing the car. Is anyone interested?Click to view attachment Click to view attachment

Maybe the shop is referring to the body/body frame and not the suspension.

Sadly it looks like the rear trialing arm mounts are gone,and lots after that.
Our cars have a very good way of covering up all sorts of issues and catch many out .
Try to sell as a whole car as parting out is a LOT of work,used to buy BMW E28's and always made way more that I paid in parts sold but really not worth the time which was way past it.
Sorry you had a bad experience.

This should be posted in the for sale section, you’re going to need to list a price there, and if you really do need to get rid of it think about what it would take to get it out of your hands .

Sorry it is not working out.
