I have personally painted by old Miata rims which did turn out pretty nice, though I'm not 100% happy with the colour. I will probably be painting them a matte black in a few weeks hear in order to look more "presentable" to clients. Any kind of painting can become very time consuming, If you are wanting a bit of a different look I might suggest looking for a used set of rims online. You are looking for a 4 x 100 bolt pattern (same as the 4 bolt civics) and something in a 15" or 16" rim. My only word of warning is that you need to measure the central hole of the rim to make sure that it will fit on the aveo. I had endless issues trying to get my Miata rims to fit, and ended up having to machine them out myself to get them on the hub. You should be able to find a used set of 4 for under $200. These will add much more personality to the car then a matte black steely will IMP.
