Beware of Sixt
We got a flat tire due to a nail. We had the tire repaired at our cost. The tire was 70% worn. When we returned the car they went over it with a fine tooth comb. Even scratching off pieces of dirt from the windshield looking for chips in the glass. It seemed like they were just looking for something to charge us for. Even though the tire was repaired and holding air just fine, they charged us 100.00 for a new tire. They didn't speak English and we didn't speak Spanish. They were done with us and put us on the bus back to the airport. I tried to deal with Sixt customer service in the USA and it was a big waste of time. I would never rent from Sixt again...never.
