I had exactly the same thing happen to me last Memorial Day. This time it was a new mousetang GT vert.
We were side by side at a stop light. He with his top down, me with my windows down. It was one of those great days, not too hot, not too cold. He looked over and nodded. I nodded back, just thinking that he was acknowledging a nice ride.
The light turned green and he floored it! Smok'n tires and all! Caught me kinda by surprise! Well, I hammered ol red and we took off! By second gear I had caught him and by third I was past him.
We were both heading for the on-ramp to the freeway and had to slow for the 90dg turn onto the ramp. I let him pass me once we got on the freeway and he gave me the thumbs up!!
I don't usually street race, but this one I could not turn down!!
You always hear that one cause of the King's demise was it's benign look. Sometimes it is cool to be stealthy!!
