Well I have to say I don't think either are particularly great shots.
The first one doesn't work at all for me, I would have liked the camera to be positioned higher so as to capture the full curve in the road where it dips. Sure, the car is nice and clean, but the rest of the shot is a bit of a mess imo. I'm not sure about the mix of colours either...
The second shot is much better, but still far from your best.
Sorry to be critical but that's how I see it.
