Will the below parts of a sedan fit on my avant just as well? (yes? dumb question right!?)
Hood
Bumper
Fenders
Radiator Support

What target prices should I be going for? (esp. hood and bumper)

 

I don't know about prices, but yeah, those parts should be interchangeable.

 

like sineo said they are indeed interchangeable. check for cars being parted. hood usually goes for 250-350. bumper with all the grilles usually go for about the same. both fenders may cost up to 400 for the pair. rad support i have no idea but i'd think about the same as the others if not cheaper. make sure you check out audizine and vwvortex as they have more members than AF.

 

I found a bumper and hood with hinges at a junkyard for $650. *shrug* going rate I guess. Blue apparently, I'm going to be awesomely two toned for a couple of weeks.
