I picked up my 350z last weekend after wanting one since they were launched and the wait was worth it!! 56 plate Gunmetal GT. I've only done a couple hundred miles in it so far but have noticed a 'noise'.. it may be completely normal but I've read a few posts on here about gearbox bearings and the like...
It's only really noticeable at lower speeds/rev's as it's not overly loud but it sounds like the old AM radios used to sound back in the day.. when you accererate you get a 'whirring' sound. Only happens when accelerating, so no noise if cruising or idling on the drive.
It's my first proper 'sports car' (as my 2 year old son likes to call it) so that may just be down to the larger than average engine and all the machinery that's needed to keep her tame enough to drive... anyway... if you have any idea's please let me know
Cheers!
