There are owners reporting their Xs are in perfect condition. How did that happen? It confuses me that some people are having problematic cars while others are having perfect condition. The only way to find out is to compare them side by side, look for in details. Some owners might be too excited that they over looked the problem, but problems like door not opening and closing, braking not working, AC not working will hinder driver from normal operation of the car. So... still don't know how Tesla manage to mess up part of the production while keeping the other group "flawless".
