Apparently I have nothing better to do, so I looked up some Minneapolis clist ads: right here in the top ten is a set of Dunlops on steelies from an '06 Mazda3 for $300!

There's also a couple other relavant ads: one with 17" wheels off a speed3 for $300 and another with 17" Dunlops, so that'd be a decent set up for $450+M&B. The wheels actually look sweet, too! Happy searching
