theres a reason theyre called limited editions. lol. i had my 04 up around 140 before wetting my pants and slowing down. the needle was still moving quick enough to where i wouldnt be suprised if the needle didnt start to slow down til the mid 160's range. the guy who said 173 seems about right. those mercedes and audis just get to obscene top speeds for the money they cost when you remove those faggott governing cables.
