I think the wild card for me will be the price. I really like my loaded GT, more than any other vehicle I have owned and didn't expect that. My guess is that a comparable S650 will cost north of $60K with little or no discount. Mine is almost paid off.
As an owner of a Velocity Blue, I would likely trade it for a Grabber Blue, with the same options. Atlas Blue is pretty darn good too. I think its a tad bit darker then Velocity Blue. Of curse Bimini Blue, the color of my 92 Mustang, takes the cake. This was taken in 93.
