Interesting..... I'm just 23 and although I have a squeaky clean record (thank god for defensive driving) my insurance on my vette is lower than it was on my Camaro and even my truck! You have to think that not a lot of young people have vettes they are less ticketed than mustangs and fbodies so insurance is a little better I have full coverage on my cherokee and my vette for under 120/month
Oh and another FYI although highly debatable on corvette forums a base model LS3 vette (08+) will outrun a C5 Z06 and can be had for the same price or less than a low mileage C5Z
