Ever since learning about AutoSlash from a colleague, my husband and I will not rent from any other company. They not only check all the various companies to find the best rate, but after you choose a vehicle, you can register it with their tracking service and they will continue to search for an even better rate!!! I don't know any other company that does that. As well, with my ever-changing work schedule, our travel plans always seem to change so we appreciate their free cancelation policy. Their customer service is available through email and is quick to respond and very helpful. They're truly wonderful. They've recently started to offer the same service with hotel rooms and although we have not yet had the opportunity to use that service, if it's anything like their car rental service, I'm sure it's wonderful.
