On the interstate, saw a white C5, chased him down. This was at night, and there were no tail lights ahead of us. he hit his brakes to get next to me, i shifted down to second about 3k. he floored it first, then i hit it and started to pull on him fast. this went on until i was halfway through 4th gear, then i had to slam on the brakes because there was a pickup in front of me with a lightless trailor . anyway, i got about a half a car on him in that short span, and i was happy. i am assuming the C5 was totally stock. Good Times.
