About prices, I compared prices in Sweden of a new Audi A4 and a Tesla S as normally cars are much more expensive in Norway, but for Tesla it's cheaper in Norway. I have not checked any rules about taxes or such, just got the prices for the same model from audis and teslas regional web pages.

             Sweden   Norway
  Audi A4    33 269   64 843
  Tesla S    70 798   55 682

Are there any legal restrictions for Norwegian citizens to go and buy cars in Sweden (then drive home)?

[pi-rat]

Yes, you are required to pay import tax on the car when you bring it into the country. In the end you break about even. You could of course bring it in and avoid import, but it's high risk, sooner or later you get busted for driving and owning a car with swedish license plates as a Norwegian. (A foreigner can keep his car here for about 1 year before getting Norwegian license plates.)

[gsnedders]

No. But one would be required to pay customs duties (import tax, really) — so then one is paying the same amount as just buying it in the country.

Bummer you have to pay import duty when importing from Norway to Sweden.
