how much they run in the US?

The GT-R is at least $90,000. I haven't priced one recently, but all the car magazines I read when it was introduced said $90K easily. Once you add in a few options, you're easily over $100K, but the high water mark should be $110K-$120K.

Brand new, they start at 96k and change. The black edition costs 106k, but the dealerships set the actual price and vehicles in high demand with limited production often come with a premium price tag. If you're looking used you can find them in the 60-70 thousands dollar range

I've sold 5 Nissan GT-R's. Anywhere from $1000 under invoice to MSRP. I was just in the Nissan store the other day and they have a new 2013 GT-R (non- Black Edition) and the basic GT-R is now the Premium as it was known. The MSRP on brand new ones hitting the showrooms are $100,025 or about there. Typically dealers want to move these very fast because they are expensive for Floor Plan. If you offer a dealer invoice + $2000 they should bite. It would be an almost $4,000 with holdback, minus any floor plan expenses.
