The central locking on our own Cinquecento Sporting has always made me giggle (why have central locking in a car where you can reach all doors/door locks from the driver's seat anyway - including the tailgate?).
But you've gone one better with power assisted steering - that being on a vehicle which weighs about the same as a pint of milk. Haha [8D] I didn't even know there was sufficient room for it in that engine bay.
Good luck with the sale though, Jon. Great little (correction: tiny) cars they are, these.
