tbh I'd forgot the mot on the missuses puma last year...was four months overdue, didnt realise until I came to tax it online And im also a tester of 9yrs I think what it is, when your a tester you do so many tests, not just for work but also friends/family that you lose track of your own cars mot date....dont help when you've got a few cars as well. I was convinced that ours was September...not May as it was
