You jammy jammy ******* !

There's a million and one car hire companies in both Bariloche and Mendoza, which from recollection were costing about $20 per day for a compact.

Not sure how many of them would allow one way drop-offs - it's quite a long way. And if you're in Mendoza, be sure to go to see some of the wineries - dolium was particularily cool

have a great time !
