how bad is the rust here?

I'm in the same boat as you cremmenga.

I have replaced my frame rail from the radiator support all the way under the floor boards. I have panels for both rockers, both rear wheel arch, and a whole new(used) rear hatch end.

The frame rail was Factory NOS I got a deal $250

The install cost about $2,000 (had to fabricate part of the wheel well to weld to)

GT28r..... Unless you have a lot of money and time, buy a car with no rust in good working condition.

If you buy a car with cancer, you will feel sorry for it. You will fall in love with it. You will eventually spend so much money on it, that you will quickly be past the point of no return.

Although you will appreciate your car greatly when you are done.
