It frightens me too! Although my own machines don't need MOTs, I do try to keep them up to a good safe standard. However, a farmer down the road is quite happy to codge his similarly aged machines - bad brakes, smoke and oil from everywhere etc. I suspect most of the members of this forum would be, like me, prepared to pay out to make the vehicles safe; though there will be others who see it as a way to save money - after all a pound a week saved is a lot
I think I'd still go to a garage and have the car checked by a tester - in much the same way as I tend to check and change safety-related items on the car before I have it tested, just to catch any mistakes I might make!
While my machines are only on the road for a few hours a month (or even a year I suspect), perhaps a full modern MOT isn't absolutely necessary and a "lighter" test would be adequate with less worry about some of the "environmental" considerations!
If the test goes altogether, I fear there will be more unroadworthy cars about (as JPB says). If this increases accidents, I suspect the usual government knee-jerk reation - "Someone was killed by an old car, let's ban them" - in much the same way as Part P and PATS, shotgun licenses etc.
Glad to hear the Minx went through easily Minxy - though that was a foregone conclusion (I hope)!
