Tesla has not re-certified the car as I don’t think it’s worth it to at the price and being able to work on most things of the car and having a tesla mechanic that I know. There are no bubbles on the screen which is actually the updated MCU which I got when retrofitting navigation. The contactos haven’t been replaced as the best of my knowledge but it was a CPO I bought in 2015 so I’m not sure. If you would like to pm me your phone number I can give you some before and after pictures but the left quarter panel, right fender and right side doors were replaced and the right quarter panel and driver side rear door were repaired.
