If trend is anything to go by, $5-10k over sticker might be the average a year from now, if we're lucky. Right now dealers are still holding out (for the most part) for the next $20K+ over sticker...connoisseur.
On on positive note, there are close to 500 out there in the wild or on the way so far. Hopefully the pool of "**** you money" buyers dries up before long.
