I have owned an 03 50th anniversry ed. and now a 05 c6 z51. GM bought back the 03 after it stayed in the shop for 90 days! However, the same issues seem to plauge the c6. Car was tight for 6,000 mi. now I get incessant body flex noise over dips while turning, rattles in the rear hatch area and a popping sound around corners from the rear end. Dealership has had the car for 6 weeks replaced removeable top, rear bushings and relubed transaxle. Car still sounds like a rattle trap. Eveybody says theirs is quiet! I can't believe I got two "bad" ones in a row. So, is this normal for vettes? Are their any after market fixes as the dealership is clueless. Any and all suggestions would be appreciated as I waited for 40 years to own a vette and don't want to give up! jk
