Although I've kinda lost a couple of days on the MOT without noticing.
She was first registered on 29 March 2001, meaning her first MOT would have been due on 29 March 2004. I booked her in for her first MOT on 22 March 2004, naively believing that they would forward-date the certificate to the anniversary of her registration. That would have been the case if I'd been advised to take my logbook in with me at the time of the first MOT.
So, it wasn't until I collected the car today, realised that they had dated the MOT to start today 24 March 2005. So I checked, and found out that I've actually been driving the car without valid MOT for two days.
