Does anyone know if the standard metal retractable roof on the 2005 SLK 350 can be switched out for the panoramic glass roof? I called my dealership and they said that they could not do it, but to check with after market body shops.
@Seanhump has been musing about this for some time now. it looks like the r172 roof is similar the r171 roof so it seems to be possible. No one has tried this yet so no one knows for sure if a r172 roof panel would fit on a r171.
The r171 does not have software support for Magic-Sky but if you were able to get a non-sky control r172 roof then if it fits it should work. Another option is to get a r171 panel and get a glass roof installed via custom fabrication/modification.
A MB dealership will not touch a job like this with a twelve foot long barge pole so do not waste time asking them. Focus on specialized 3rd parties that do custom work on high end cars. Will not be cheap but I think it is possible.
