The G10 is a great little camera. I had a G9 that I purchased for my honeymoon and it took some very good images. Since you bought it to take pictures of your car I think it's enough. If you want to get more into photography you'll want to look into a SLR. Check the POTN forums (photography-on-the.net). Lots of info there.
Have fun with it and post up some pics
