Jig work costs
 

My 2000 VW Golf TDI was involved in an accident that requires that the frame be "pulled" straight with a "jig".

I'm looking at doing all the body work myself.

What would be realistic costs associated with getting the car pulled straight on a jig at a shop?

Most likely more than the car is worth.

Also, I thought unibody cars could not have this done.

You can straiten unibody cars. Look in the yellow pages for frame shops. Good ones make the rest of the job easy. Also dont cut anything off before they pull it, like a quarter panel or frame horn. Let the frame shop do its part first.
