If you do import you car to Switzerland (I'm going to assume you're coming from the States), you can do so duty free, as the two countries have a free trade aggrement. Hire a company, Schumacher Cargo is pretty good, and they'll bring it across to Rotterdam or Antwerp and then train it down to just near the airport. Depending on where you're coming from it will cost a few thousand USD, probably between 2000 and 4000. You'll also need a few documents to retrieve the car, as well as proof that the car meets Swiss regulations when it comes to construction and engineering. All this should be available on the customs web site.
In a nutshell though, I would say sell your car and buy a new one here if you find you really need it. It will be expensive, and parking will be a problem, regardless though.
