The Bonneville GXP wheels didn't have rivets. That's what they are, unless someone made an identical looking wheel to them. Someone on CL had chrome ones listed around here a couple years ago. When I inquired about them, he said the car was his mom's, and she had asked the dealer to chrome them when she bought the car. Apparently, they didn't do a very good job because they were pitting like mad from what he said (never saw pictures, they sold before he even got a chance to send them to me because he was asking so little for them).
