To me taking mot early is a "least worst" option, particularly if the car is a daily?
Allows time to plan:
repairs, order parts, schedule garage work and any associated loan car off them, budget...all while you are still mobile? Maybe even allow time for some diy?
Works for me.
On the other hand, my old cabby is in for mot while i am away on holiday, so ready to use if any summer still remains when i return home. I do this to avoid the spring time rush, when all such "classics" are being reactivated
