I've had a lot of experiences with g35's (stupid dam warranty work!!) and those things haul ***. I once raced a m3 cabrio(top down) in a 05 G35 with aero kit. I drafted and passed his *** at bout' 140. If you're thinking about buying a 06', dont you will lose serious money on it. Reason being is that the new 07's are coming out very soon and, that car just brings the G35 to a totally different level.
