Greece Car Rental

So my wife and I are planning a trip for 2025. The only thing causing me some anxiety is the car rental. We need to get from Pireaus to Gytheio so we thought we we road trip the family. Then I read about all the dodgy practitioners.. over charging insurance, double charging insurance, charging people for preexisting dings, etc, etc..

I did read somewhere about the prospect of getting my own 3rd Party Car Rental Insurance.

I like the idea.
