Wow! Those are some great numbers. Among the highest that I have seen for a stock 500E. I wonder why the factory numbers are so far off? The only thing that I can think of is they are giving a worst case scenario which in a M119 can be pretty bad when the engine is hot. It is rather neat/amusing that an 11+ year old luxury sedan can beat mustangs and camaros. I still want to get some 1/4 mile numbers for the 400E. I will say that some of the newer cobras and the Saleens sound awesome. I was driving (in a 300D T loaner) to class on Tues. and I see this car bouncing from lane to lane behind me and I'm thinking "that's sort of a waste in this traffic" until he gets near me and revs it under an underpass. Oh my god that thing sounded so wicked it gave me goose bumps. I don't know what year it was but it said Saleen on the bumper. I totally got why he was weaving in and out of traffic. You can't drive a car like that without punching it all the time. The previous owner of my C36 put 3" pipes from the manifolds back with a 3" Magnaflow muffler because of the turbos but I can't stand the sound. I suppose some people like that but it is just not my cup of tea. Once I get my inspection sticker I'm taking the muffler off and running straight pipes which you can do apparently because the turbos deaden the sound or getting another muffler system. I actually liked the stock AMG sound a lot. IMO Virginia has a bunch of Nazis making the vehicle laws. They don't have a maximum db level but rather make the police officer be judge, jury, and hangman by giving him/her discretion as to whether the exhaust is too loud. Same thing for window tint 50%??? Lame. A bill to reduce it to 35% was withdrawn. What lobbying group kills window tint? Cops or was it just too much revenue??? If it's cops just make a law that says you have to roll down your windows when a police officer pulls you over. Did I mention they passed a law making NOS illegal?
