Taking a car off the road....

I am selling my wifes Beetle as we are moving out of Switzerland for work, but keeping our house and another car here.....what do I need to do about taking a car off the road. It's currently in my garage and I have recently received the road tax demand.

And what if I want to drive it to a dealer for sale? Can I do this as in the UK without tax on a pre-arranged appointment.

Many thanks

Cancel the grey card at the StvA and get "Tagesschilder" if you want to drive it to the garage. Or the garage can pick it up.
