Interesting that a few people have been trading in Roadsters for Model S's... Frankly I do not understand the mentality of that... If you need a sedan, buy the Model S in addition... Keep your roadster, it is a work of art and in the long term collectible and a fantastic car to own.
Anyways, the Tesla Store said they were shipping most of the used Roadsters back to California... Is it that there is so much demand for them there? Is there an investor buying up all the available ones for his time capsule to resell them for 5 times as much when they become more historically important? Is there a secret plot to crush them like EV1s?
It would make sense to keep them dispersed to save shipping costs.
