Nice car!
Nice pics...I can't wait for the snow and frigid temps to go away so I can get some work done on my car. Some quick tips on photographing cars that I have picked up/figured out: Try not to take pics of the shaded side of the car/into the sun. If you do, use the flash (some say you should always use the flash, even when it is bright outside). The falsh won't completely light up the shaded side of the car, but it might help throw a little more light. I also tend to keep the tires straight or turned away from the camera in most cases. Another tip that I learned is to get low when taking pictures of a car. squat down or get on a knee so you are at more of a the level of the car. Taking pictures down towards a car doesn't yield great photos most of the time (unless you are specifically trying to catch a certain portion (reflection off a hood, etc.). If you want to catch some good reflections, getting on a knee right at the front fender of the side of the car with the sun and aiming down the side of the car will bring out the reflection quite well, though limiting the amount of car actually in the picture. Having the sun low and coming from behind you will help as well.
I am no expert on photography and have made many of the mistakes (and continue to) I have tried to help you with above. Just some things to think about.
