Holy crap talk about overpriced. There's a new 2010 427R on ebay for $43k and almost all of the buy-it-now's are under $50k. Sweet car none the less.
You can buy a 2010 GT500 for sticker ($50k). Check ebay - you'll find plenty for no markup, and I've even seen a couple slightly below sticker. Right now there are 2 for $48k and 2 for $50k, all for their buy-it-now price.
