Not only can you not spell segue correctly, you have consistently overlooked there was a period in late 2020 to March 2021 where the UK got refresh cars from Fremont followed quickly by the first shipments from Shanghai, so we were able to directly compare build and paint quality of the refresh cars. The Shanghai cars were consistently better, in fact there are YT videos from UK-based Tesla aftermarket dealers doing detailed walkarounds talking about the fit and finish of said vehicles.
Now, we are completely prepared to accept that Fremont have subsequently upped their game and are now producing cars of comparable quality, but this is irrelevant to the OP because he is looking at buying a used car in exactly the time period I have just described to you.
