Does anyone know if the seats from a 560 SEL can be put in a 300 SEL? Are the heaters in the seat itself or is it something that can be removed and put in a 300 rear seat? If that is possible what kind of nightmare would it be to wire this up? Would the 300 be prewired or would everything have to be installed? I would like to have the rear seat heaters but the reclining end of it is not so important. Anyone have any expierience with this sort of thing?
