I now see from reading the reviews that many other people how experienced the same scam as we have with Sixt Car Rental. We rented a car in Portugal. The car was in terrible shape at pick up (many dents, a lot of mileage, cracked windshield) but we were tired and just wanted to get going, so we didn't complain. We drove it for a fairly short distance and it had a blow out flat tire. The incident cost us a full day of our holiday. They eventually sent a tow truck and a taxi to take us to get a new car. Then when we got home, we received a HUGE bill for damages. This is a an absolute SCAM! DO NOT ever rent from these people!
