I recently rented a car for 3 days to go to the south of Portugal. The price was $8.77 total. That was the second cheapest option because they also had a $6 one. One thing that was additional was the collision damage waiver which reduces or eliminates what you have to pay in the case of an accident. However, there are many credit cards that have this benefit. Two that I have are the SPG card and the Chase Sapphire Preferred (CSP).
Check the fine print and exclusions
Both had similar wording, but the SPG terms said that you have to be a permanent resident of the US. I think I am, but since I am in Lisbon for school at the moment I was not sure. However, I read the CSP terms and they did not include such language so I booked with that card.
The booking conditions said you do not need an international driver’s permit if your license is in the Roman alphabet, but you would need one if you are from USA or Canada. However, I had read information that you wouldn’t need one. So I called to make sure and they said just my license would be fine.
What I did neglect to read was there was a $25 fee for a full gas tank. Fortunately it was only $25. However it brought my rental to $34, not bad, but maybe not as good as I could have got.
