Can buy a new 07 c6 for low to mid 40's with no trade and it is so much nicer in every way than a c5. I know, my opinion, but I have owned both.
Have to be one heck of a driver to tell the diff in a c5 Zo6 and a C6 (speed wise)except the C5 rides and drives so much worse and scrapes every anthill in the road plus just does not look cool when you park em side by side.
Had 11k miles on my 03 50th anni edition and one test drive in the 06 is all it took.
Was blown away by how much difference there was after an aggressive test drive. So much lighter feeling, better riding and S.O.P. faster feeling, I almost couldn't sleep till I found one optioned like I wanted.
Mustang feel in a GT is not even in the ballpark.
Feels more like our trucks BIG and HEAVY!
But thats why they call em trucks not sports cars
