I would love to pick one up, but the potential cost of repairs is enough to frighten me off.
My friend that is currently a mechanic at a VW dealer (who previously worked at an Audi dealer) says you can expect a $1,000 repair bill just about every time you need to bring it in.
Now if the transmission fails on you (which has been known to happen in the '04 models), expect anywhere from a $4,000 to $9,000 repair bill.
Undoubetly, when the price drops low enough, I will pick one up and hope for the best - it's just too much car to pass up.

If I get it cheap enough, and get enough use out of it before anything big fails, I'll just scrap it if the repair is too costly.
