This is more of a didn't get killed story. I was headed south on a rural four lane in East Tennessee when a late model Corvette pulled on the highway. He caught up to me and ran side by side for a minute or two. He then kicked it hard, I had no passenger so I thought "what the hell". I was doing about 65-70mph when the Vette nailed it, so I nailed it too. Traffic ahead in my lane, so I pulled in behind the Vette. I was about two to three car legnth's behind since he got the jump on me. I hung with him through the traffic, then open road ahead. We were doing 125-130mph when he then I let out of it. The whole thing only took a minute or two, but it felt longer. He never got more than four or five car legnths ahead, and I thought the Caddy held its own. I pulled up next to him and we exchanged waves. I did motion for him to roll down the window and as he did I said "Bet you didn't think a Cadillac could hang with you". He smiled and nodded in agreement. The Allante Northstar didn't get killed, but I felt pretty good. I must have been a C-5, because the Z06 would have chewed me up and spit me out. I just wish that we could have hit it at the same time.
