Very classy. I like the black and white with the Mercedes. Also the locations for the shot's add a ton to the concept. Did you think this out before you did it or did you take the photo's and then decide they would look great B&W in post?
I really like 2 & 3, the first is a little harsh with the contrast of the sky but still a nice shot. It may just be the upload process, but I'm seeing some grain that would be easily eliminated in LR.
I'm not a fan of car photos that have a background that competes for attention with the car.
I suggest using selective focus (shallow DoF for a blurred background), and/or use a background that is very plain so it does not compete with the car for a viewer's attention.
