Hi there! I've seen that some cars in my country (Portugal) have some accessories that are quite rare here but very common on other countries. I would like to know if I can retrofit those on to my car. (W202 SW - S202 - Esprit - C220CDI) I want these:

• Cruise Control - heard that was a stalk to be installed and programmed by software (?)
• Rain sensor (for auto wiper)
• Lights on sun visors' mirrors
• (any recommendations ?)

Can any of these be performed and how can I proceed?

Thanks in advance 🙂
