Quick couple of things for those coming to Switzerland and debating bringing their car.

1. UBS (at least in Basel) do not do personal loans, mortgages only.
2. Leasing finance companies will not touch you if you are on a probationary period for your job.

So if you want to use a car and have a 3 month probationary period you can

a. Bring your car with you
b. Pay for the car outright
c. Obtain the money before you come or from your existing bank.
d. Do without a car.
e. Public transport everywhere.
f. Hire a car

Worth knowing I think.
