Pretty obvious and the same as house ownership (full time). Why sell out the roof over your head without somewhere else to go, regardless of how it is constructed.
I should have said, we want to import a van but ad said. Sell first, rent somewhere, buy a car to get around then sell said car when van purchased so replied to myself really.
It might be cheaper to trade in as suggested rather than paying out to rent & then buying a car that you will probably lose money on when you sell. Buying abroad is rapidly becoming more expensive. Since summer we have gone from 70p=1€ to 78p=1€ & with the current uncertainty it's only going to go one way.
