I think this is a bad idea, every 2 or maybe three years perhaps, but not a complete wipeout.
younger people are generally less practical and don't do maintenance, these are the ones more likely to have cars in the later period, and more so moving forward. Even if you're a bonafide mechanic, we all make mistakes from time to time, The one thing an MOT does is confirm a second opinion on safety critical items . . . . not many people can test brakes at home, and the MOT rig will thoroughly check steering/suspension as well.
Although it does mean I can take the race car for a quick road test
