Thank you very much for your information. I don’t have the new C140er. Distronic retrofitting is therefore too expensive for me. I have a heater with remote control and it’s also really fun at the moment. On comfort, however, every S or CL driver likes it but also wants good look, plan in the spring 19″ or 20″ wheels with spacers because someone has experience how to drive it afterwards? Should you pull 19″ or 20″ on it with or without spacers and enn how many mm are to be recommended per page? Let me inform you about drivers who have experience P.S. If you’re a bit stöbert say some don’t go out about 17″ in no case such a thing, chassis suffers comfort etc. is this really so bad?? Ok admitted is everything quite expensive but I like it easy and for something you save yes. Bye. johnny
