I booked a self-drive tour in Tromsø. After comparing prices, I found Europcar on Ctrip to be the cheapest. I ordered a Polo, but was given a Kia Niro PHEV, a model not available in China. It was new, with 15,000 kilometers, and had heated steering and seats. Highly recommended. Although Norway had a lot of snow in January, the main roads were cleared promptly, so if you drive carefully, it wasn't a problem. I arrived at the airport at 10:30 pm. There were two lines ahead of me, and I waited about 20 minutes. The rental car agent was very attentive. I registered my personal information, saw my driver's license and a translated copy, and was given the car. I paid a deposit, which was quickly refunded after I returned the car. I picked up the car with a full tank of gas and returned it with a full tank. Europcar in Tromsø is open until midnight.
