2003 Smart cabrio roof parts?

[Dinky]

Hello, I'm new here and new to Smart cars. I've brought a lovely 2003 Smart Pulse Brabus Cabrio and the roof doesn't work. I've got a mechanic friend to look at it and I'm missing a motor for the roof on the passenger side, I only seem to have one. Both the roof motor covers are missing too with wires hanging down. Does anyone here know where I can get a motor and roof parts as my mechanic suspects that the mechanism which pulls the roof back is also broken. Any help or advice would be gratefully received.

Sorry, seem to have posted this in the wrong year category but I can't seem to move it. I'll post again in the right category...
