Ill show you mine when its finished.
I have a 260RS, in black. What i'll be doing to pretty it up a lil is to give it a two tone job, by painting a pearl over the black, from the bodyline (near the door handles) and up, so including the bonnet and roof etc. Or, vice versa, from the bodyline down.
This is fairly cheap and easy to do. Im thinking an aqua pearl, or maybe a dark blue, just something that stands out a lil, and a pinstripe along the join in about 1/8th inch. The pinstripe will coordinate with the pearl eg if its a dark red pearl, ill run a dark red metallic pinstripe.
Can add to it by throwing some glitter in with the pearl and so on. Then re-clear it, obviously. The pin stripe is to A) provide a tidy line to break up the two colours and B) neaten the two finishes, as where you have painted an re-cleared will sit a lil bit higher.

PS Street Commodores did this to their monaro. Was flat red, they just made a glitter and orange pearl mix for the top half of the car, looked mint. For a commo. Nice finish on it, anyway.
