I rent cars regularly as I travel for business. Figured I'd give it a try. I would suggest against ever using this app. The car rented died on me three times in traffic and after I return the vehicle I was billed for fuel I did not use. You cannot dispute any charges they can charge you for whatever as you sign a clause stating so. This interior is a great idea if it was executed properly but it is not. Be smart stick with rental companies that guarantee a safe vehicle
