I always use Ards. My bike is due it's first MOT (its got a massive 3,800 miles on it) and it will go to Ards in January when I get around to booking it. Our MOT is harder than on the mainland UK, what with the automated ramps shaking the vehicle to test bushes etc. Also all our test centres are government run and not just a local garage which means standards are higher and for example we can't get a broken bulb fixed if it goes, we just get failed. Though we don't have to bother with it till the vehicle is 4 years old.
