I don't think it was meant entirely seriously
And btw, yeah i think the gash in the sidewall will fail the MOT, but don't know how people can say that it'll fail on the tread as well. As stated above, there needs to be 1.6mm of tread across 75% of the middle of the tyre.
I said what I said as I've read that such things are true!
Anyway, my statement still stands, that a car has a full MOT does not mean its in great condition.
