I just saved about $200 total on two separate car rentals in Greece, one 3 day and one 4 day. My benchmark is a superb Hertz rate that I normally use, and that rarely can be beat. I ran the rental dates thru AutoSlash just to see, and my jaw dropped. The other company (Dollar) wasn't onsite at the airport, but met us in the Arrivals Hall. Returning the car was a bit trickier; we had to meet the person outside the terminal. It was worth it given the significant savings.
