Powder coat. It can look really good if you get the right color (don't listen to the negativities of some on this forum) - I've seen a few 370s with it done and it's cool - and you don't need to buy whole new rims to be unique.
Not everyone can afford to spend four-figure sums on wheels. There's no shame in that. If powder coating is comfortably in your budget, do it dude!
