have fun with the Smart Roadster Jimmy - we have the Fortwo Cabrio and it is a lot of fun.
If you haven't found it already, a lot of useful information here -
https://www.evilution.co.uk/You do have to pay for some of the more detailed information , but it it is generally worth it.
Also, the very worst leak on the Roadster lets water into the 'SAM' (like the ECU for the car).
Most of these should have been sealed by now but it is worth checking as the SAM is very expensive to replace......
