We are thinking of going to Argentina early next year and having gone that far then perhaps over the Andes and into Chile by hire car and flying home from there in due course. The problem is that one-way car hire from one country to another isn't possible (not in this case anyway). Apparently the most convenient crossing for us would be over the Uspallata Pass, which as it happens seems a stunning road. What I would like to know is whether there really are car rental depots on either side of the border posts which would allow us to get around the problem, all the ones I can see are way up in the Andes and far from civilisation- the border between the two countries does run along the tops of the Andes after all. From the searches I've done it really doesn't seem like there are any such posts, my search brought up such unhelpful results like Car Hire in Buenos Aires and then Car Hire in Valparaiso.
As planning is at an early stage if you know of any other border crossing that do have convenient car rental depots I'd love to hear about them, but if not it isn't a deal breaker, we can always cross back into Argetina and fly out from whence we came.
TIA

) came from Madryn, just a few miles from where I live, and the landing place is named Puerto Madryn which is now twinned with Nefyn, our village. They still speak Welsh there and in the past few years there has been a resurgence in its use, in fact the daughter of my wife's friend went there a few years ago to teach Welsh through the medium of Spanish. She's back home now and still teaches the same course via the internet.
