8th Gen Antagonist
Not really an issue, but something I discovered that I thought was odd. So I change the oil all the time on our fleet cars, and am very familiar with what size wrenches I need. The 2002 impalas take a 15mm, and the 2006/7 impalas take a 13mm. Well, my coworker bought an 08LS and had me change the oil, damn thing is a 15mm! Why on earth would GM have changed it midstream?
