The Z/28 sounds great but it just does not look as smooth as the ZL1 in the small video portions I have seen.
The ZL1 video's on YOUTUBE and GM's website in the ring look much smoother then the Z/28. Admittedly, they are still dialing it in but I think they have more work to do.
I can say that it does not look as if it would be that comfortable to drive on the street as stiff as the ride looks in the videos so far. I am hopeful and optimistic they can live up to the hype they have created
because EVERYONE is watching.
