I applied the same logic when I used scrabble under our cars years ago. MOTs always seemed to fall due in the winter when it was cold, wet and miserable. One year I had a lightbulb moment and booked them both in for tests in the middle of the summer. Mysteriously, reliability seemed to improve significantly.😇
(before I get inundated by comments along the lines of "you should have bought an XYZ model" I'm talking about an era when 50K miles was good for an engine and Volkswagen sold their NEW cars with a 6 month, 6,000 mile warranty.)
