Smart Roadster/Coupe gearbox

[AndyT77]

On my everchanging shortlist of potential next cars, is the above. Preferably in Brabus guise. However i have heard from people in the trade (i used to work P/T at a MB dealership), that the gearbox can fail, resulting in a hefty repair bill.

Can anyone shed any light on this, for example what the issue is, how likely is it to happen and how much is the repair likely to cost? Thanks

Hmm, so maybe my mind is put to rest regarding the gearbox, but what about this 'B' service? How often is that, and how much are you looking at?
