Will this car fit in my shopping bag?

It seems like a strange concept so, naturally, I'm intrigued. As a self-confessed shopaholic and car fan, the idea of a used car supermarket appeals to me on more than one level. However, surely the idea of a supermarket for cars is a little over the top? They don't fit in your trolley and you can't carry them away in a shopping bag, so what makes it a car supermarket? I guess it's because they have a bigger choice, rather than because they sell baked beans!
