Err...

Correct me if I'm wrong, but this will do nothing to the second hand market. Why? The scheme says you have to have owned the banger for a year. And the scheme only runs until March. Ergo, you can't buy a banger now and get the discount, and those of us already driving one are doubtful to be able to afford a new car. So this will achieve exactly what the government were after: Free headlines.
