Piss poor fit and finish of most of the exterior body panels. Waviness in the door panels. Every Z that I've seen has the A-pillars looking like they were hammered into shape along the edge where the door glass is. The doors in general don't line up with the rest of the car. The 94 - 96 cars are worse than the earlier years. I never would have spent $30k - $50k on a car like this. Nissan lost it's way for a number of years.
It's still a beautiful, well engineered car otherwise.
