If you put enough monkeys in a room full of typewriters, eventually they'll come up with the complete works of Shakespeare. And if you put enough Fiat 500s and Lamborghini Murciélago in the world, eventually someone will make them one.

Don't believe us? Have a look at this. On top, it's an over-inflated classic Fiat Cinquecento. But underneath, there's a 580hp 6.2-litre V12 Murciélago engine. Which is a bit silly.

It's been built by the chaps at Oemmedi Mechanics, and they have form with this sort of thing. They've already built a Ferrari 3.0 V8-powered 500, and one with a Porsche engine.

What's your ultimate car/engine combo, TopGear.commers?
