Had so any its hard which one to choose but my favourite was :
I Had a 300bhp turbo nova last year and I was on my way down south,
I had a motorbike trying to get me to move out of the fast lane when doing about 90mph, So I dropped it into 4th turned the boost switch to number 5 and let it have it. I pulled away but he only chased for a bit so I moved over and let him past, he pulled alongside and gave the car a quick glance, then went to rip of into the distance, lol
Dropped it into 3rd and had a neck and neck race to 7200in 5th where I was slowly pulling away at about 6500 which is about 140mph.
I was laughing my head off when we slowed down, we slowed right down and he was trying to shout to my mate about something ( probably what the f**k have you got in that !)
Was a good laugh and quite scary too, but good to see what the car was really capable of, bike was a GSXR600 as when we slowed right down we could see the graphics,
Not told as well as your story but u get the picture !
