'07 Mean GXP - 5,200 miles. I had the car into my Pontiac dealer for its 2nd oil change & I spent a good deal of time inspecting the diff. while it was on the lift. I saw no evidence of any leakage, and have heard no unusual noises thus far. It's been the best new car I've ever had - I haven't had to have anything repaired under warranty at all (knock on wood, spit on horseshoe, cross fingers Yada, yada, yada...)
See how well it reacts to some dragstrip thrashing (I found my helmet a couple weeks ago...)
