Large companies are more reliable. Demand was high, so I had to wait half an hour before getting a car.

The car was very new and the pick-up process was very convenient.

The attendant at the San Francisco airport car rental counter had a poor attitude. After declining to upgrade the car model and purchase fuel and insurance, he barely looked at us properly. Since we arrived at night, there were few vehicle options, and the available cars were relatively old models.

We booked a Jeep Grand Cherokee or similar model, but when we arrived, the staff said there were no Grand Cherokees available and gave us a Hyundai Santa Fe instead. However, we saw a Grand Cherokee parked at the exit. We specifically told customer service that we needed a car for Death Valley and Yosemite, but they didn't give us the Grand Cherokee and instead recommended an upgrade for an additional $30 per day, which we refused. On the way to Las Vegas, the weather was very hot, and the car's RPM would exceed 3000 every time we accelerated slightly, forcing us to stop frequently. Moreover, when climbing the eastern entrance of Yosemite, the car nearly didn't make it, with the RPM close to 4000, scaring us quite a bit. We've rented from NATIONAL and AVIS before; the cars were always in great condition and matched the models on the website. This time, the experience wasn't great, which might be a case of 'you get what you pay for'. Buying directly from the rental company's website is almost twice as expensive, so I accepted it. I won't choose ALAMO again.

Highly recommend Alamo! When you exit SFO airport, take the escalator on the left or right side and hop on the shuttle train directly to the rental counter, very convenient. We added $5 per day for roadside assistance. It was secured with a credit card, and in about 10 minutes, we went to the parking lot to get the car. The key was inside the car, just ensure you have your driver's license and contract ready, as you'll need it to leave. On the second day in San Francisco, our car window got smashed near the Palace of Fine Arts. We reported it to the police, then drove to Union Square to try to change the car, but we were told we had to go back to the airport. The car change process was quick and hassle-free, and it was free. We got a new car with only 2400 miles on it, which was even better than the one we had before. Great service! We returned the car at LAX, drove straight to the parking lot, and it took about 3 minutes to inspect. Then, a shuttle bus took us to our hotel. This rental company is awesome, and we will choose Alamo again in the future!
