Hello guys, I have discovered a few pictures of a S-Coupe (W140) which has been converted e.g. convertible. Can someone give me exact information about it? e.g. -where you can have it remodeled -what it costs -much more detailed pictures if you have to carry out such a conversion yourself, which requirements have to be met so that the TÜV is OK? What are the costs for the TÜV acceptance? I thank you for your contributions!
