I would refinish the wheels in a gun metal color which I think you can do with a duplicolor can. Might take some trial and error. A few coats of clear so it won't fade after washing/rain. Paint the calipers red and add some PORSCHE decals on the doors in a dark grey to match the wheels. And I'd paint the roll bar hoops the same color as wheels -- check forum sponsor Klisstle, the paint would be DIY.
A lot of bang for very little buck with those mods.
