I've also got a Smart Roadster, although mine's a notchback, rather than the Coupe. I've fitted Michelin Energy tyres (40psi) and removed the antenna so far. I've got a big list of stuff to do, just not got round to it yet. I've been planning a coupe conversion (without the big hinges) and a few small changes, like taping up the gulleys behind the doors and removing the mirrors.
