I think it should become law that if a car is bought second hand via private sale, that if it develops a faults after the sale, we can politely ask for £50 back???

Of course if we can pay the seller the sale price less £50, it isn't even upto the seller if they refund £50 cos they haven't got it to refund?

Also, if we are rumbled we should come a PF and lash the seller just because he has the cheek to myther for a measly £50?

Would this be a good new law? Please discuss....
