Mr. Chubbs,
I'm very shocked at your impression on the suspension. It's my MOST favorite feature this new 370Z. The suspension is all aluminum and VERY responsive. Therefore, you feel all the bump in the road and it's a good thing
. I am going to guess you drove the sports model with wider tires. (?) Does your dealer have a Z with 18" base rims? give that a try and see if you like the thinner tires better.
Can I suggest 135i?
P.S. We will never hate you! You're our ambassador from England.
