So I had a fun sprint with a 2001 ish Mustang GT on the hwy today. I was about 2-3 car lengths ahead when I punched it in 4th gear around 70mph. I was at the end of 5th at about 135mph when he caught up and at 150mph in 6th when we ended it. He was 1- 1 1/2 lengths ahead at 150mph. Now I have raced plenty of stock GT's and beat them no problem, he had to have been modified? right? Also we had a friendly wave at the end and went our separate ways.
