Dont believe in the prices.
Cons: As most car rentals, you always have the felling that someone is taking advantage of you, trying to smart you out. And this is what happens in this place. The price that it says on Kayak is not real, cause they force you to take a basic insurance that will add at least $150 to your price. This is a kayak problem as well, that should provide the final price overall, or specify which car rental requires an insurance and which doesn't.
Another problem here is that the car that they promise or even similar is not the same. For example, on my reservation I requested a VW Jetta or similar, and when I got there they gave me a Seat (you probably never heard about it) so when complained and said, ok so this is not the same, they said that they don't even have the Jetta that Kayak was showing, and the Jetta that they had was a different category ( more expensive, of course).
Horrible car, horrible experience, a lot because the car rental is sketchy and also because Kayak should provide better information to their costumers.
I would suggest go to one of the rental companies that you know and trust even if you'll have to pay a bit more, at the end it will even out, since this place hide all the other fees.
