I do remember reading a while back that the law had changed on Section 59s for the worse.
Apparently a random member of the public complaining about your driving is enough to get you slapped with one. No appeals process, no evidence, heck, a police officer doesn't even have to witness the alleged incident! Just think, a few complaints from a busy body who dislikes you/your car could be enough to have your ride seized regardless of what you were or were not doing. Awesome, huh?
I was expecting to get absoultely hammered with tugs when I bought the GTI. Young lad in SE London driving a 80s hatchback with a fart can, I couldn't help but think of the worst. Luckily no problems to far. I do know the second I get hit with a S59 the car is up for sale - Remember, a S59 sticks to the vehicle, not the driver!
