Pleased to say that the car has passed yet another MOT with zero advisories.
It was due the MOT at the start of April but due to the continuing backlog here caused initially by faulty lifts (
http://forum.a8parts.co.uk/showthread.php?t=15474) and then the virus, despite booking over a month early, the closest date I could get was the third week in May at a centre 65 miles away. Of the 15 centres we have, there was only one that had a slightly earlier date, and that was 90 miles away.
Anyway, job done. Now, a little test, brought about by doing some prep work for the MOT. Can you identify the mystery bolt? The only information you get is that it is approximately 68mm long. Bonus points if you can guess how much I spent on tools getting it out? MJ is excluded as she knows all about it, since I pestered her with questions.
