Our app - the Smart car designer has made the big time - its been ranked the "Big App" in the Sunday Times.

Smart, the mini-motor in the Mercedes stable, has a bespoke design service named "Tailor Made", from Brabus, whose tweaks are more usually applied to Maybachs. Tailor Made is also available as an iPhone app. Once you've used it to spec your Smart Fortwo - any body panel or interior section can have its own colour, you can share the design with other users or take the phone to a showroom and ask it to make you a Smart for real.
