Very convenient. It was early morning when I got off the plane, so there was no queue and I picked up the car directly. Because there was no C class, I was given a BMW 3, which was acceptable.

Due to a security incident at Frankfurt Airport, the entire airport was closed, causing the flight to be delayed. Upon picking up the car, I was informed that the booked and prepaid car had been rented out. Only one similar model was left, which required an additional payment of 5000 yuan for an upgrade. Communication with customer service was unsuccessful, and I had to pay extra to get the car.

Arriving in Frankfurt full of enthusiasm, I had to walk quite a distance to collect the car, which was a C4 Cactus with a 1.2L gasoline automatic transmission. I had to find it myself in the parking basement. The car had only 8900KM but felt old and small. Upon inspection, I found damage on the side mirrors and hood, suggesting I was being scammed. I immediately reported it and got a yellow tag for the damage. Driving on the German autobahn was a disaster, as the car roared at full throttle for thousands of kilometers over 21 days and couldn't easily overtake other vehicles. It felt like a gardening vehicle suited for an old Frenchman in the countryside. The 1.2L engine lacked torque, making it impossible to climb even small slopes in parking garages. I nearly hit cars multiple times when the car rolled back during refueling. Thankfully, with 20 years of driving experience, I used the handbrake technique to manage. Choosing Frankfurt as an entry point turned out to be a mistake. The rear windows couldn't open, making it very unsafe, especially for female drivers. This car rental was the worst part of our one-month European trip, despite the beautiful scenery and nice hotels. Avoid believing the big companies' promises and free upgrades; Hertz gave me the worst car, and using QEEQ was just a waste of time and money.

Hertz company is quite good. Even when an accident occurred, they managed to coordinate and resolve it without affecting our subsequent trip.

The vehicle was in great condition and fuel-efficient as it was a diesel. The staff were friendly, but there was no one to accompany me for an on-site vehicle inspection.
