Polished wheels look better with the chrome caps they were intended for, and they aren't that expensive. Install what's supposed to be on there and leave it be. Drilling any holes to mount different caps, or even painting the wheels, is going to make for a very tough sale if you ever want to get rid of them.

As far as painting the wheels black, you may as well buy a set of steel wagon wheels for that and keep those for your offroad setup. Leave the aluminum polished.
