I won't rise to the debate of police officers just getting their quota, persecuting the motorist etc etc etc.
Suffice to say I've attended plenty of fatal collisions where mechanical fault of a vehicle has been a contributing factor. Ironically often a problem with the braking system.
Have a chat with their families and see if they think anyone taking a chance driving without a valid MOT who gets a ticket is hard done by.
As for the original poster who took a chance and got caught......
No, the make of car on the ticket will make no difference, though by all means feel free to fill in the back and request a court hearing.
There is every chance a magistrate would be infuriated by such actions and reward you with a much larger fine and possibly some points to go with it.....
It's quite simple really. Abide by the law and keep your car road legal. It can work out alot cheaper!
