Sameero, thanks for the info. I figured it was an easy fix with the right instructions.
Natskiboy, no frame on these cars. They are unibody. And yes, the unibody is bent to heck in the rear. To Volkswagens credit, the crumple zone did its job. The damage stopped just behind the rear door. The roof did not buckle as some cars would do in a wreck this bad.
SurfWagen83 is right. I bought this car from a salvage yard. It is my fourth wrecked Passat that I have bought. One was a parts car and the first two were repaired using parts from that car. In the end after fixing the first two I had the rear of the parts car left so I bought this wreck. It'll be a "rear clip" where the body shop cuts the car in half and welds on the "new" rear end. It's not really that difficult for them. Look at all the long limos out there. In the end, all three of my daughters will have Passats; 1 02 GLS, 1 03, GLS, and 1 02 GLX (the one in the photo.) My son has a salvaged Audi A4 and my wife has a salvaged 02 Audi S4 and I have a salvaged 97 911 Cab. It's a hobby. The only problem is the warranty is gone and the resale is poor. However, if you keep the cars for a long time it works out well in the end. The trick is having a great body shop and two friends that own a salvage yard.
My advise to anyone who will listen is to never by a slvaged car unless you knows its history. A car that was stolen and the seats taken may end up with a salvaged title and one that was cut in half will too. Also, the body shop that does the work is very important.
