Okay, hypothetical question. You are in the market for a new car. It must be brand spanking new, or pre-reg, and bought from a dealer. It can't be second hand or a private buy. You only have £13,000 to spend, BUT, you want SPEED. You don't care about image or badges. You don't care about the number of seats or the size of the boot. You just want something that has way more poke than, say, a 1.6 16v Astra G. It does have to have 4 wheels though.
Where would you spend your wedge? What's the fastest bargain basement motor around?
