Owned by Mercedes-Benz and with a reputation for making small, clever cars, Smart offers a striking, upmarket alternative to more conventional rivals.

It currently has a two-car line-up, the smaller of the two being the distinctive Fortwo, which, as its name suggests, is an ultra-short two-seater that uses an unusual rear-engined configuration to deliver the sort of turning circle that even London taxis can only dream of. It's a doddle to park in small spaces, too.

Smart's 'family car' is the Forfour, which is little more than a stretched version of the Fortwo, with a second row of seats and a larger boot. It's more of a natural rival for cars like the Hyundai i10 or Kia Picanto.

On paper, both cars come at a considerable price premium when compared with rivals, something it says is justified by its badge appeal and the technology in the cars. However, sales have been slow and there are often keen Target Price deals to be found.
