£1 million pounds of used car savings

Apparently, the used car supermarket I mentioned in my last blog post (The Car Shop) have some kind of price reduction event that woks out at £1 million of used car savings across all their stock. According to the annoying drop down box on their website, the savings are because the book price of used cars has dropped? Does that now mean that my Matiz is worth less? Not that it matters, think my little bro will be buying it.
