I thought I would share a link to another board that I am a member of. This member has taken the time to make a thread with some excellent tips for shooting your vehicle. It shows that with a little patience the right lighting situation (and some luck) we can all take some great shots. I think he stated that all the shots in the thread were made with a 3 MP camera, so top of the line equipment isn't necessary. I just thought I would pass this on to see if I could help anyone out. Remember to be patient, I take lots of bad shots to come away with a few good ones.
