They won't accept the UK MOT because the car needs to be modified hence it needs to run through a technical inspection.
According to the rules, it doesn't have to be modified

From the board outside the council offices...
"uznawane jest badanie techniczne pojazdow zarejestrowanych sprowadzonych z panstwa czlonkowskiego ini europejeskiej konfeder szwarajcarskiej lub panstwa czonkowskiego europejskiego w ktorego dowodzie rejestracynym lub innym dokumencie wydanym przez wlasciwe organy tych panstw zawarta jest informacja o wykonanym badaniu technicznym i jego termomie waznosci.
a technical examination of registered vehicles imported from a Member State and an European Swiss Confederation or a European Member State is recognized whose registration certificate or other document issued by the competent authorities of these States contains information about the technical examination carried out and its term of validity."
Not that it matters. I'm not going back to the UK so I'd have to modify the car when the MOT ran out anyway.
In some cars yes but not in the Forester SG.
You only need to change the front headlights and the rear fog (move it from right to left) and you are good to go.
Good to know, thanks. I've got the translations and paid the tax (zero in my case) and have all the forms.
Also I sent you a PM, check it out
Sorry, my old-tech setup doesn't show any PM option (or any option to change or add personal details)
