Here's a couple of pictures of the Smart Car Cabrio model, spotted on a visit to London in 2003. The design looks sleeker than the coupe - the headlights have been reshaped into a more aggressive form and the taillights have a cool wrap around treatment. The single color frame and body panel treatment really unify the design and the gradually upward sloping crease along the side accentuate the wedge shape. Not sure why they bothered with that lower little vestigial scribed line on the door though.
