I suppose that the car could be from N Ireland? Would it then have mph? I really should have paid more attention! If it’s from N Ireland that would make it a Uk car?? Not trying to be political here by the way! Car was registered here I believe.
If it was from Norn Iron, then yes it would be full UK spec with mph clocks.
We get a lot of used uk imports here into the south. Most people see the mph clocks as fine or just a minor annoyance as we also used to be mph before going all metric about 10 years ago.
Probably not many Irish cars get exported the other way though. I do know of someone who sold his Irish Golf R to a UK buyer and it had to have uk clocks fitted for your MOT.
