How Unknown compares
Unknown has an MOT pass rate of 1.2%, against 69.4% across every make in the national record. That is 920,501 tests and 11,879 since 2012 with a defect code to categorise, so the figure rests on the whole national record for this make rather than a sample of it. See what Unknown vehicles fail on.
