There are people who do it - I have a little guy just a bit younger than yours, and at first I was very much into the idea of him going along for rides with daddy. However, the more I thought about it, the less safe I think it would be to have him there with me. He'd be a lot closer to the crash energy than he would be in the back seat of a "regular" car, and he'd also be low to the ground in the line of impact (but the way the car seat lifts them up a few inches, a lot of him would be above the window line in dange). I decided that he'll have to wait until he's older to ride in a Corvette.
While I was researching this question for myself, I bookmarked a few threads on DC about car seats and Corvettes. I have them on my computer at home, but sometime tonight, I'll get those and link them for you so you can make your own choice.:thumbsup:
