Hi Resolution Pics

I'm not new to the photoshop world. been doin' it for 6 years now and been doin' renderings for about 6 months. my major problem is finding hi resolution pictures on the internet that are of stock cars and trucks. but without any reflections on the sides of them. whenever i find the angle and size i like they took the pick outside and u see a buildings reflection on the side of the truck. I was just wondering where some of you big time guys get your photos, cause i can tell from your work that they weren't you average 75 res. pic from the internet. a 2nd gen S-10 would be really awesome to get, but any rides are needed cause i just like to have fun with em. thanks
