Don't think so, but it's good for a laugh, posted at the mbworld.org kill stories section:
This is the old style, non-supercharged AMG he's got, which had 349 hp stock, i.e. not even close to an IS-F in performance, even if you add an exhaust and a pulley to it!

Anyway, I'm a proud member of the mbworld stamp-out-the-BS crew, and we usually chase bozos like him off by challenging him to replicate his amazing feat, which is what brought me here: if anyone would like to meet this guy at a 1/4 mile strip and smoke him, let me know and I'll invite him...in the event he's actually dumb enough to show and doesn't slink off and hide in the woodwork, it'd be hilarious to watch!
For the record, I've got a CLS55 and I think he's full of it.The e55 is my dd and I drive it about 30 miles to work and 30 miles back. Had a real long work week and was leaving my friends house last nite. So I then decided to do a little bit of spirited driving that nite lol. I hit the freeway and did a few nice pulls to remind me why I love this car. Nothing WOT but just enough to feel the power with the high revs. As I'm getting off the exit I see a black ISF getting ready to go on the highway, so of course I follow him. I catch up to him and we do a few pulls. We go from 50mph after 3 honks and I thrash him lol. I brake to let him catch up and then we do it again except from 80mph. Smashed him again hit about 150 before I brake to let him catch up. We rolled once more at 60, same outcome. I was def feeling good knowing that my 10year old car still has it. Btw my car is not stock.
