We've got a 2006 3SS AWD, just bought it a month ago just turned 50k. Sure is an amazing SUV and its in great shape. Bought an extra set of new OEM 20" wheels for it for the summer and the original OEM 20's for winter wheels with Blizzak tires.
Its got these crappy normal trailblazer wheels on it right now and they look really bad. The OEM 20's should be mounted up very soon.
