The insurance they have is full coverage, understood as the largest coverage that a car rental vehicle can have in Costa Rica, where any deductible (it is low but there is), is the renter. The one who tells him that in Costa Rica he covers 100% of the amount, he is lying to him.
What does it cover? Civil liability, third-party damage, own-vehicle damage, partial theft, total theft.
What does not cover? Damage less than $400 USD.
