Not many people, orderly queues, excellent service.

It's okay.

We had to wait quite a bit for the shuttle bus at LAX. Several AVIS and HERTZ shuttles came before one Dollar shuttle arrived. At the rental location, there were many people at Dollar, possibly because it was around noon, a peak time. We waited in line for nearly an hour. They did offer additional insurance, which is optional depending on your choice. Initially, we chose a Jeep Cherokee, but it struggled with uphill roads. Later, at the Dollar rental spot at San Francisco Airport, we switched to a GMC. Its performance was much better, although it consumed more fuel. The car exchange process was very convenient: just refuel, a quick inspection, and then you get a few cars to choose from, which was nice.

Smooth process, good car condition, and included a GPS.

Extremely bad experience. I booked a Jeep Grand Cherokee, and everything was OK during the paperwork. But when I got to the parking lot, I saw they had charged me an extra $67 for fuel. I went back to ask them why, and they said I could return the car with an empty tank. In the US, gas costs only $2.43 per gallon, yet they charged me for 120 liters. After arguing for a while, they refunded me the $67. In the parking lot, there wasn't a single SUV of the same class, let alone a Cherokee. Free upgrade? No way. The guy gave a straightforward answer: 'You have two choices, one wait, but I don’t know how long, two you take a minivan.' With no other option, I ended up with a Dodge Minivan which had over 60,000 miles (100,000 km) on it. It was nerve-wracking to drive it through the national park. Other than having a 3.6 engine, the car was in terrible condition. The wipers were worn out, making it impossible to see when it rained in LA. At 70 mph, the steering wheel shook when braking. It nearly caused an accident on Highway 1. It was terrifying. When returning the car, it was early morning, the parking lot was nearly full and there was still no Grand Cherokee, not even a Ford Explorer. Basically, Dollar doesn’t have these cars, so be aware. With the same engine size, whether you rent an SUV, a minivan, or a sedan, the result is the same. So, when renting a car, choose based on engine size and go for the cheapest option, it makes no difference.
