I've been looking for a new C-6 and think I've found one that almost fits the bill. I've been looking for one without the transparent roof as I've heard they can cause the interior to be VERY hot in the summer. Does anyone have any experience (good or bad ) with this top? Also, I've wanted a car w/ the Magnetic Ride Suspension which is difficult to find here in Denver CO. All I can find are cars w/ the Z-51. Should I bite the bullett and just order a 2008 or is the Z51 just as good a suspension (w/o being too harsh)?
