People with tourist visas I expect fully entitled and able to get car loans... (Edit: maybe I am misunderstanding the whole thing: is it "loaning cars" or is it "loaning the money to buy cars"?)
A car loan is usually loaning money for the purpose of buying a car, not loaning a car.
getting a long term loan to buy a car sounds like it would signal intention to be more than a tourist.
In the US, we usually refer to "paying someone to borrow a car" as a car "rental" and "borrowing money to finance a car purchase" as a car "loan".
