Well, great it passed, congrats, but oh boy I read about those MOT experiences and just scratching my head, wow. In here the tester can not interfere with car AT ALL so you can fail for forgetting to pull the seatbelt from under the rear seat or for forgetting to remove hubcaps if wheelnuts are not visible. I would freak out if any tester destroyed my adjusters as those would also snap like twigs.
mental!
atleast ur sorted
