Selling unroadworthy vehicles

Sold me a car that is unroadworthy, refuse to acknowledge that is is their mistake.

I purchased a vehicle from them, the first vehicle had a water leak and left me stranded on the highway for 4 hours.

The second vehicle the sales agent never gave me a temporary permit, when he finally did send me one it was blank.

The third vehicle had a broken water bottle and when I took it for road worthiness it failed. After complaining to them they just said that the vehicle passed their road worthiness just 2 months ago, now the question is, how do you sell a vehicle but you do not supply the valid certificates?

It took me three months to get the valid certificate as I had to pay the charges myself to get the vehicle road worthy.

Rule of thumb always take the car to the AA for a check before purchasing your vehicle from them.
