Hey guys I've just recently purchased an 07 350z and I've already encounterd a rather annoying problem... The car is fantastic however whenever I drive at around 60+ mph I get a super annoying rattle, the best way to describe it is like a wire knocking around with the wind blowing it, it's nothing like a deep metallic suspension fault and it only comes at speed, I have looked in most obvious places but am I missing something comman? I've searched the forum but failed to find someone with my problem. To guess it sounds like the rear left quarter of the car. Any help will greatly help a million
