Thx SD and MN. Kiwi, sorry to hijack your thread, but thought it may be related.
Looks like importing a car to Switzerland is duty and tax free as long as you've already owned the car for 6 months and you don't sell the car within the first year of stay. Makes sense. The website has gobs of other related info.

Vehicle owned for more than six months
If you've owned your vehicle for more than six months, it is considered to be part of your personal effects. You simply have to fill in a clearance request form for moving purposes and it will be exempt from import duty and VAT. You have the right to drive your car with foreign plates for a maximum of one year. The car is reserved for your personal use and cannot be loaned, rented or sold to a third party in Switzerland for a period of one year from the import date. If you do not comply with this condition (by selling your car, for example), customs will charge you retroactive import duty. The amount is determined on a sliding scale according to the age of your vehicle. Make sure that you are legally insured to drive in Switzerland during this period.
