I saw black X5 from far and decided to catch him. He started going 100MPH when he saw me so I knew that he wanted to play. When the road opened up he jumped to the right and stepped on it. At that time we were doing about 60PMH. I hit it too and had to back off because I was going to run in to him. Next the left lane opened up so I went. I easily pulled on him. When he saw that it was 4.6 he slowed down form 110MPH to 55MPH. He had black 4.4 non sport. It was fun. Now I know that 4.6 was worth extra $. Happy New Year!
