About 1200 miles on mine and no major issues, except for one that I caused myself, which was a broken fuel flap and a nasty little ding as a result. Ding repaired by Dent Wizards (fantastic job he did too) and fuel flap on order. In another post, though, I mentioned the following:
One thing that happens is a knocking noise that seems to come from the rear passenger side. It only happens when the car is cold (first start-up of the day), does not happen straight away and within a few minutes it is gone.
The car makes other odd noises too, sort of like me when I first wake in the morning. Few rattles noisy brakes and a noisy engine. Once warm, though, most of the noises go away.
Also noticed that while driving at speed a couple of times that the car sputtered a bit. I had been messing with the gas cap/fuel flap so I attribute that to getting air in fuel tank or not having the fuel cap seated well enough.
