Black cars are the toughest for photos in regards to reflections, but these aren't bad. Last 3 look like the white balance is a little off on the cool side. 2,4,5 (my favorite), and 6 I think are your best. 6 is pretty good, but I think could have looked a little better with the car a little closer to the camera so that the bridge is more in the background and the car really popped (maybe one with the hood closed from that angle too). 1, 3, and 7 the crops are kind of boring. I like to leave more space in front of the car, but that's a personal preference thing. 8 and 10 have ugly foregrounds that distract from the car. 9 the car is underexposed and the sky is overexposed. Not much you can do here unless you wait until the sun is down further or use a flash (extra tough with a black car) to light up the car.
