The best thing to do is to get a side shot of the truck, then you cut just the truck out using the lasso tool or using the extract feature in photoshop. Then, nudge the cut out selection down to where you want it. Make sure you dont cut out he wheels, so when you nudge it the body of the truck moves, and not the wheels and tires. To change the paint job, you select the truck and go to edit>adjust>varitations... There are many other ways of doing it but that is probably the easiest. That will keep the lines, shading and everything. If you need me to do it I can do it real fast if you give me a side shot of the truck.
