If so, has it been modified in any way, shape or form - even something as simple as non-factory wheels? Have you added indicators to a historic motorbike so make it safer? Have you added smoked tailights? Has a previous owner changed anything?
If you have and you live in the EU, in six weeks your car will be illegal to drive. And no, this isn't scaremongering.
A law is being passed denouncing any sort of modifications as un-roadworthy, making millions of cars no better than scrap and putting hundreds of thousands of car tuners/fitters/mechanics out of work.
Quoting from the Department for Transport document:-
The Commission proposes to introduce a definition for a roadworthiness test that components of the vehicle must comply with characteristics at the time of first registration. This may prevent most modifications to vehicles without further approval of the vehicle. (this will apply to many components and to all types of vehicle)
The Commission proposes to change the definition of an Historic Vehicle that may be exempt from periodic testing. This may allow vehicles older than 30 years to be exempt from testing providing the vehicle has been maintained in its original condition, including its appearance.
The characteristics they're talking about? They want everything to be as factory-standard as if it's just come off the showroom floor. No more generic car parts from Halfords. MOT prices will go up; repair prices will go up. Hundreds of tuners/modifiers/mechanics will be put out of work as what they do will no longer be legal, and millions of cars will no longer be 'drivable'. It will be very difficult to make any car over 30 years old safe to drive on the roads, due to a requirement for 'original' parts. There is this horrific myth out there that modified cars are dangerous and that seems to be what they're trying to crack down on. While I'm as sick of chav-tastic Corsas that can't go over speed bumps without bottoming out as the next person, this will also affect all the modified cars that aren't silly.
You can read more about the proposal here and there is a forum with ideas about things you can do to protest this nonsense here.
N.B. This is NOT a Eurozone-bashing thread and if it ends up being P'n'R'd I won't be pleased. I'm trying to raise awareness of a very important change in the law which will affect millions; not start a UKIP debate. If you want a UKIP debate, go get yourself guilded up and have it in the Politics and Religion section.
