Correct me if I am wrong but not many car manufacturers would have cars that are built to different specs parts, designs? but with the same 'model names'. Is there any reason why the Performance Model Y is £10,000 more expensive. The upgrade probably costs Tesla only a few £100! Power increase is software. Springs cost the same just shorter. Wheels and red brakes will be the dominant cost. Unless....we are paying for those spec changes? Giga casting and structural battery pack mods from Berlin. Apparently demand for Performance isn't huge....really! The UK are being taken for a ride.
