About 30 years ago I took my XJ6 for a MOT to a garage (part of a big chain) near where I lived in Bath, when I went to collect it I was handed a long fail sheet and an estimate for £1,000 for repairs. 1st item on the fail sheet was 'leaking rear shock absorber' when I asked which one, I was told "left hand" I again asked which one to which the manager rather annoyed repeated "left hand" I then informed him that XJ6s have 2 shock absorbers each side at the rear and all 4 were dry before I took it for the MOT.
I asked the manager to put my car back on the lift and went through the fail sheet with him, resulting in a fail only on hand brake adjustment which they adjusted while I watched.
Unfortunately for the garage the person who gave licences to MOT stations at that time was a good friend of mine, and when I told him of my experience he paid a visit to the said garage which ended up losing it's MOT licence, and ultimately closing as most of its business was 'repairing' cars that they had wrongly failed.
