Yes, these "old men's cars" are surprisingly fun to drive... Too bad they have such a "cheap", aesthetically unpleasant interiors but such are ALL of American "sporty" cars. Partially explains their relatively inexpensive prices.
I really only see old men driving a base or vert. The majority of the z06 and zr1 owners I know are under 40, but then again we are talking about people with wana-be supercar aspirations vs some retiree's weekend ride. On the other side, I also met up with the corvette association for a local get together years back, and oh god, piles and piles of stock base models, with tacky chrome add-ons, who scoff at the guy who added a CAI, and shun motorwork like a sin, so I see where that stereotype comes from. I love the looks, the c5's do have that late 90s-early 00s look to them, but hey, that's when they came out, but to each his own, c6 look great, c7, I have yet to see one in person... again, my own opinion. My goal is a Ford GT in the next few years, but for now, I love having a daily driver that can pull >1g in a turn, >500hp, >20mpg. The interior (you can see the imgur album linked above) is getting a full makeover, insulation matting, new Kenwood 6990, new seats... You figure a car that can brake, accelerate, and turn better than all but a handful of cars, would have a seat that would keep you in place (added later as an option), my z-28, g35, even my accord, had more lateral support. For a daily driver, maintenance and parts are cheap and readily available, it has an LSx motor lol, I got exactly what I wanted, and won't feel bad putting lots-o-miles on it, unlike other cars.
