I was in the freeway and I saw this IS 300, he thought his **** could run so I was like **** it. He pulled along beside me going about 60 and we hit it. I took the lead all the way to 120 and got out of it due to traffic. By that time I had at least a 2 to 3 car lead on him.... I am running stock. My conclusion is that a IS 300 with or without a stick is no macth for a CLS. The IS cant make up the difference even if it has a stick, that comes out in 2002.
