Hi all. I was wondering how would a w211 E55k fair in terms of out and out pace when compared with the latest e63 biturbo. I am considering a brand new E63 biturbo but at the moment just can't get my head around the looks, in my opinion from some angles it doesn't look too bad but from others to me it just looks butt ugly. But on the other hand my just keep the 55 and go down the eurocharged route ie, pulley map headers etc. really don't know. If I change it will be in august. I have test drove the e63 biturbo and it didn't seem an awful lot quicker than the 55. Dilemma ?????
