I was 40 when I bought my Vette in 2003, with less that 7000 miles on the odometer. I must admit when I bought it a C5 was an option, but all of the used ones in my price range had very high miles. Then, I went to look at a C4, in which the owner also had a C5. They were sitting side by side in his driveway, and the C4 held it's own in terms of styling. Then I sat in both, but the C5 did not give me the sports car feel that the C4 did. So buying a C4 is not a matter of just affordability, its also about how the car make you feel. Remember, from the C4 down, Corvettes had a unique style. When the C5 appeared, there were references to an over grown RX-7. Now that the C6 is here, some say it looks live a Viper. Also it's a shared platform; that new Cadillac. So back to the point, I rarely see young people in C4s because they like those SUVs.
