Photoshop help changing Camaro color

[67Rally]

I think there's probably too much light and shadow on the side profile of you Camaro pic to get a good idea of what the McLaren Chicane Grey will look like, plus the color of two McLaren's you posted appear quite different.

**************Edit***********

I take that back. I just did a quick sample and I think it will come out fine. If no one else posts one for you, I'll do a good one later today for you. Of the two McLaren's you posted, which shade do you like the best?
