Getting worried now, was thinking I should sell this year due to the 15k miles p/a I do to go to work and back but think my parents have talked me out of it (they know how much I love my Z). So if I'm keeping it, quad exhaust conversion, aero skirts, this diffuser http://www.bimmerfest.com/forums/showthread.php?p=3526945 and possibly the aero spoiler! - not exactly saving money! :driving:
