To add to your driving comfort, why not install cruise control? Now that average
speed cameras are becoming ever more common, cruise control may be more a necessity than a luxury. This addition
will require a TAN from your local smart dealer. The exact price of the TAN varies but expect to pay around
£100. You only need the following part in this mod:
Cruise control and wiper stalk (SQ0012540V004C96A0)
Physically, all you need to do is replace the existing wiper stalk with the cruise control one.
