First time owner '08 3LT, Z51, dual mode exhaust, with Nav, etc., crystal red. I liked the C5 styling, but the C6 is so much better without popup headlights. Performance at this price point is amazing. The ride with the optional Z51 suspension is still very smooth, yet taut. Dual mode exhaust sounds simply awesome when you punch it in the guts, and adds a bit more power to boot. And who knew that a car capable of nearly 190 mph could get 25-30 mpg when driven normally. Amazing. And the trick integration of the HUD with the nav unit is super cool. I have very few negative things to say about this car. It's a keeper.
HUD + navigation integration. Having driving directions pop up on my windshield is the ultimate gearhead geek. Crystal red is sexy in the sunlight. Keyless system is nice, still getting used to it.
Auto up windows, Nav is hard to read in some daylight conditions/angles with outside light.
