frame straightening help

[Ndralle]

So I traded my 190d for a 190d Turbo. The problem is that the Turbo has a good amount of body damage. The previous owner rolled it backwards into a tree.

I took the car into the local community college and the instructor said that frame is bent. While they have a frame straightening rack at the college, they do not have Mercedes frame clamps. The local shops want 250$ just to look at the car and another 100$/HR to straighten it.

My question is... is there anyone on hear with the ability to straighten my frame for less $? Would be willing to rent me the clamps?

Any ideas?

My instructor said the damage doesn't seem too bad and the car probably only need two pulls from the rear.
