I was headed towards the in-laws for dinner yesterday, and I ran into one of these on the road yesterday. It was a really nice dark red rag top with the top down, and a really nice sounding exhaust. Looked like this old guy was giving his grandson a ride in his car. I caught up with him and tried to pace him for a bit to give him thumbs up, but he didn't look over. So I thought, whatever, and proceeded to move on. Well up ahead, the light started turning red, so I quickly slowed down and lined up next to him. I looked over and he just stared blankly ahead. Just before the light turned green, I saw him out of the corner of my eye, lean to his passenger and say something. Then the light turned green and he gunned it. I didn't have time to launch, so I just stepped on the gas. I stayed even with him until about 4k, then I pulled 1-2 cars on him. When it shifted to 2nd, I pulled many more cars on him and I think he shut down at that point.
I looked up some info and I guess they run 17's stock (4 speed auto trans) to around 9's heavily modded. I'd say he had some light work done, nothing big.
