i can't believe this thread is still going, wow
i started it over a year ago and havn't checked it since

it is extremely off, my counting

i did it with a g-tech and my 500E with a g-tech, i can't remeber exactly what the 300SEL was, but i remember it was somewhere between 9 and 10 seconds

my 500E did a 5.64 0-60 and a 14.1 1/4 mile with the g-tech
