A 4.0 megapixel camera is fine, you just need a tripod for the non-flash applications you were using it for. Tripods are so worth the investment if you like taking photos of your car and exposing the picture more by leaving the shutter open longer. I prefer longer exposures and more ambient light rather than the flash. Get a tripod and you can take those pics and it will not be blurry.
This is both a compliment and a challenge...I am not insulting you at all. When I saw the firt few pics with the cool photoshop fx, I thought this was an all-tricked out custom car and was surprised to see it mostly stock. The angles and backdrops for your pics were good too, it was almost a disappointment to see a normal LS there hah. I have a pretty much stock LS too so I am not busting on your car, it just threw me for a loop. WHat mods are you planning to do (when and if money allows)? I am hoping to get some clear lenses in the headlights and a better looking grill as well as new mufflers and an intake. Maybe some on the windows tinting? A spoiler and LSE body kit would be sweet too...but that is particularly expensive and not in my budget anytime soon.
