My Focus is pretty much blacked out already, no chrome except the grill. The door handles, window trim, roof antenna, roof rack are all black. I like it with the all black steelies for winter too. Probably with a dark tint and some black chrome wheels it would look interesting, but I think doing the grill in black would be odd looking.
I think it could be a decent looking car with some coilovers to lower it a bit, bigger wheels, tint, but it would also be just flushing money down the toilet, or most likely reducing resale.
