"those £0 cars are not going to be allowed much longer - read this and prepare for £140 a year if you buy from 2017"
To play devils advocate for a moment, that was always going to be the case. The scaled down VED bands for zero and low emission cars was always intended as a carrot to encourage people to choose those options. I don't see a flat rate coming back in the near future, but the banding rates will go up as planned. It may be that this is happening sooner than planned. I don't remember the details now.
