I propose that vehicles that are regularly serviced at authorised repairers according to the service booklet norms set by the manufacturer are exempted from the roadworthiness test.
I think this makes sense because the manufacturer, who sets the norms for servicing and inspection of the vehicle, is much more familiar with the vehicle and also knows about the faults and defects of the vehicle, which are known and checked by regular garages, but at MOTs the professional inspection is sometimes (also in my experience) unprofessional.
Of course, when registering the vehicle, the owner should be able to show that the vehicle is roadworthy by means of a certified service booklet from an authorised repairer.
I should also mention that I had my car inspected and the gentleman who inspected it did not even know how to start it, even though it is not a rare vehicle. However, as a second car, I drove a car that had play in the taillights and forks, and this too was not detected by the same establishment, and the car passed the technical inspection. After 1 month I took the car to the dealer for a routine service and we fixed the chassis play, and the dealer wondered how I had even passed the test, and I was not even the first such case.
