These are two completely different cars and no fair comparison can be given.
I have owned all the Zeds from 2003 up.
I have also owned numerous Vets including C5, C6 and ZO6.
Loved them all, but no comparison ever made.
The Vet wins the road presence dilemma all day long.
Remember that the Vet has leaf springs, however, that should not concern you as you appear to be more concerned about road presence.
