Be careful what they are not telling you. They will give you the absolutely bare bones package and
as I found out the hard way in Spain one time, I had to dig a good bit deeper to pay for the 'extras' as I was told.
A few things the Cartrawler people do not include can surprise you.
Check the fuel policy, milage, travel out of country and so on.
Insurance is a favourite, make very sure you read the small print on if you damage the car.
Say good bye to your excess loading if you as much as chip the paint.
That is your contract with the car company, not Cartrawler.
