they look good on that silver one and the black one just makes me think of knight rider which is ace. not sure on the merlot tho i think its the siver rim with the black star that does it. a bit of a hint of having a white band around the tyre sort of thing for me.
cant say im convinced on black wheels on red cars. maybe a bit of a traditionalist as i like big shiney silver unfussy wheels. on the silver car it deffo look good tho.
