[embee]

Interestingly, the tester told me verbally that both headlights were too low, the MOT report online says both too high and too far to the right. Doesn't mean much but just another oddity.
The emission test has the time on it, unfortunately the MOT cert doesn't have a time so I can't compare when the cert was filed and when they phoned me but it was almost 40mins after the emission test. The emission test is usually done near the end of the MOT in my experience.

My mind is made up, next year all my cars go to the local Council MOT station, they don't do repairs so no vested interests.
