I guess "I don't want you to buy" isn't working? I have a 2002 Z28, and I've driven a few Camaro V6s(mid 90s), and I think he'd be ok for the most part, especially if he's going to buy a V6. The only part I'd emphasize as being more dangerous than a Honda is if you drive it in bad weather with bald tires. This is obviously more true with a V8. But, really, you can kill yourself with a .22 caliber pistol even if a .45 is far more powerful, so in the end the biggest factor is your son's behavior behind the wheel.
I have a Honda, a pickup, and the Z28. The Z28 is easily the least comfortable(and least fuel efficient, but the gap is small enough that that'd be a non-factor), least practical, and most prone to scraping the bottom coming out of the driveway/parking lot, etc. For me those are good enough reasons hat if I had to get rid of 1 of those 3 vehicles I'd be choosing between the Honda and a Camaro, but I'm obviously older than your son.
