Some parts of Tesla’s vehicles are occasionally assembled after they’ve reached a dealership, distinguishing the automaker from the industry standard. According to the Financial Times, dealers may receive vehicles lacking “key parts” like seats and digital displays.

Those parts are flown to Tesla’s dealers so that local employees can install them before delivery. This may seem odd, but it’s the result of Tesla trying to deliver the most up-to-date vehicles it can.

Finishing the assembly at a local dealership isn’t always how Tesla functions. It primarily does this when an updated component becomes available after the vehicle ships out from Tesla’s manufacturing facilities.
