Hi and welcome.
Yes, we all like owning the car... Just work yourself through the forum, to get this feeling.
Service 'down the road' is almost impossible. Even tire changes might be challenging. They could help you, filling the water for the wiper.
But you are in Switzerland, home of the Emil Frey group, the big European Fisker importer... They will guide you to a CSP to get help.
...and yes. There are some minor drawbacks... you might get stranded and have to be prepared to live without the car, for weeks....
Although, the Revero will use or mimic most of the Fisker Karma parts, there might be a shortage in the future.
But anyway, if it isn't your spare money, do it!
