2 points here.....
1) an MOT is only valid as of the moment it is issued.
I think that MOT documents state that " items may fail soon after an MOT due to the test" - ie shocks etc.
2) it is a dealers legal responsibility to sell something that is "of merchantable quality" & "fit for use".
That vehicle does not appear to conform to either if those legal requirements, in my opinion. Unfortunately my opinion dont count for Jack **** .
I am well aware of that i have done hundreds of MOTs. At time of test only applies. But it does not take the brain of Britain to see that there is a little wrong when a vehicle fails a test on certain items, is documented then passes later that day presumably with the faults corrected. But turns up three months later with exactly the same faults it failed on still apparent. All this ringer crap is just that, crap. Unless the tester is in on it. But all this happened BEFORE the dealer bought it it would appear. So his crime is saying he has had the vehicle checked over when he obviously has not. Or if he has selling it in that condition knowingly. He can't possibly wriggle out of that one either way.
