While the rate was ok for the type of vehicle we rented, it was very disappointing to get a low tire warning within 2 hours of having the vehicle and a warning that the diesel was in need of special attention within a day.

If we didn't know what to do, we would have wasted over a day of our trip having this rectified versus the 1/2 day it took for us to track down and make necessary adjustments on our own. We lost hours and the company did not even apologize or have an excuse for their car not properly prepped before renting it to their customers. Sixt is, obviously, not trustworthy nor concerned for our safety. read more
