UK Car Finance Agreements if move to Switzerland (and other loans)

Hi, looking to move to Geneva later this year for work (I'm a UK national moving from the UK). We have relatively new cars each, both on finance, that we want to bring with us. I can't see in my finance documents (or any of my other loans or credit card T's & C's) that limit where I live once the finance has been agreed. Does anyone have experience of moving to Switzerland with existing finance agreements and loans in place in the UK - and did you have to do anything or just carry on paying as normal ? (just from a different, now swiss, bank account). With the cars in particular, the finance agreement is a PCP deal - one of the options of the car finance is that you can return it at 3 years at a pre-agreed price. If I bring the cars to Switzerland I expect that I'll have to 'permanently export' them as it'll be longer than a year. Would this nullify my PCP agreement - or would I simply just not be allowed to export them with us? I have asked the car company, but they're taking their time getting back to me...
