I dont see why the picture above cant be used. If you want to find a better picture off the internet thats fine but it may have other issues. If you are after a particular color try and find someone that might have that car in a certain color. You will have a color closer to what you want so you can adjust it easier.
Black is one of the easiest colors to shift. White is one of the hardest, at least to make it look decent.
I wouldnt worry about the scratches or rust. Focus on the big areas such as color and wheels.

The tough thing about the starting pic above is that there are far too many places that need clean up to make it look "right". And if you simply "paint" over the scratches or "smoothe" it, those sorts of things will become extra obvious when you start to do color shifting. See, in really good images, there is a consistency and evenness to the grain of the paint (based on the pixelization), and when you do touch ups, the touch-ups don't have the same grain. And by the time you fix that, you'll have spent tons less time just finding another image to work with.
