On those two particular models, which have been out for a good while, the sales have been quite low.
According to Autocar:
Reviewing Tesla’s latest move, Dylan Setterfield, head of forecast strategy at Cap HPI, doubted the decision to stop imports of right-hand-drive Model S and Model X cars would have much impact on the appeal and values of cars currently registered.
He said: “There are relatively low numbers of both in the UK. Just over 11,000 examples of Model S were registered between 2013 and 2021 and less than 6500 Model X between 2016 and 2021. These figures pale into insignificance against the more than 90,000 Model 3s already on the roads and the more than 80,000 Model Ys, which will have been registered by the end of this year.
