did you post a WTB thread in the proper section? honestly, the MKIV wheels are nice, but for the price, you can probably get some used aftermarket wheels with tires for the same price, just post up a WTB thread, and keep a look out on the FS Section.
IMHO, new wheels/tires are a lot better than buying them used. it's a little bit more expensive, but well worth it. retail pricing puts my tires @ around $1800. i spent a LOT less than that for my wheels. It was WELL worth it to me.
