hi mate and welcome by the way,
Iif it is an import and was first registered in the UK then it has been here a while, and depending on the quality of the importer and there underspray wax coating abilities, you could find some rust about make sure to have a good look about underneath the car for rust and also signs of overspray paint if it has been repaired anywhere!
also if it is an import to add to plummermans post when u lock the car the wing mirrors will fold in automatically this was never an option on UK cars, my knowledge on import models is not that great but im sure all JDM cars had that as standard.
just check it out and then as Plummer man said do some research into the UK equivalent and mileage etc.
Good luck
