I had a thought before... if you really want to tart it up, get some pearl or candy colour put in the paint. Then it will have an extra dimension to it. I'm not talking about the chameleon paint that looks like three different colours depending on what angle you're on, just something to make it look better than just a really shiny shiny car.

And there are lots of different types of window tint, not just the obligatory grey. Among others, there is also reflective tints (some silver through to grey, and bronzey yellows), and almost holographic tints.
