The car worked well, and the checkout process was well done. THe people at the counter were extremely patient as I needed to check on Collisions Damage Waiver, etc. with another company. The coverage offered by Kayak at the bottom of the confirmation email was much less expensive, so I definitely recommend taking this if you want coverage.
Optional coverage was outrageous. Signage to return the car was poor. It's marked something like Rental Car Shade or something strange like that.
