You really need to communicate well with the rental company about the insurance issue. When picking up the car, they pushed for an additional insurance of 146 Euros. They said if you don't take this insurance, you have to leave a 2400 Euro deposit. It was really intimidating, and I couldn't reach you by phone.

It’s a good car rental company! Overall, it’s fine! They patiently explain various rules to you. They won't give you the car until you listen to everything! When I returned the car, I left my phone inside. When I went back, they returned it to me! Icelandic people have a high level of integrity! But make sure the rental car has a towing rope, you’ll need it in Iceland! If it doesn’t, ask for one just in case.

No Chinese service, and they tried to upsell insurance. If you don't buy their full insurance, they hold 11,111 euros on your credit card. We were in a hurry and didn't argue with them, partly because of the language barrier. It seemed impossible to hold such a large amount, so we didn't pursue it further. The GPS provided by the rental service was mediocre; our phone worked better. They gave us a Jeep with over 60,000 km, and its condition was really poor.

We didn't see any Green Motion signs at the airport. After asking the information desk, we waited about 10 minutes before seeing a shuttle driver holding a Green Motion sign. The drive to the pick-up point took less than 10 minutes. There weren't many people in line, but the efficiency was low. There were various sales pitches for different insurances.

The service was good, with no additional upselling.
