Fellow Audians; I had a crazy thought this weekend and figured I'd throw it out to the experts. I heard about a 1993 Audi 100 CS QUATTRO Wagon that's for sale and I started wondering how difficult it would be to transplant the engine/transmission and associated and necessary parts from my wrecked (in the rear) '91 Audi 200TQW into the 100 CSQW. TIA for your help and expertise. Greg.
