Best kill was in my 350Z bone stock at the time against a Porsche boxter S (mods ?, probably stock). I was with my girlfriend who hated me racing. So when this guy drives up beside me I ignored him until he swerved at me. He had his gf with him and she was laughing along with him at us. Needless to say my girlfriend told me to "smoke this prick" so I drop down gears and start to take him on the outside lane. By the time we get on to the freeway I had 3 car lengths on him so I slowed down and this prick flips me the bird to we go again and he finally quit when we were going in and out of lanes at 120+.
That was the only time she ever ok'd me to race with her and she started to understand my love of racing a little better.
