Haven't done yet in e46, as I have yet to take delivery of my car. However, let me share with you a short experience I had before Raya 08. I was at the North South HIghway to KL cruising at 120kph, when there was some interesting sight appearing before my rear view mirror. 5-6 cars were going at high speed, so my gatal foot landed flat on the throttle, chasing up the pack.
I did 180kph in my Honda City 05' Vtec, prob still have room to go up to about 185kph in stretch between Slim River-KL. Honda Jazz idsi allowed me to pass, followed by Sentra, Myvi and others which I can't remember. But wait...this is not the drama, of course. Right far infront of me there's a kilat white car....I can't believe it to see how it maintains in front of me all the time. I think you wouldn't guess it right....its a brand new white Proton Saga 1.3cc 2008 model with all the plastic covering its seats still. Worse, 4 adults inside.
I couldn't chase them and lost them when I arrived somewhere in Rawang.
I posted the sale of my Honda City last week.
