Our experience with SIXT Iceland was better than expected. We expected the worse when reading all the comments on Google and Trustpilot. Because we had no credit card, we applied for two credit cards before our trips; this was not necessary - SIXT Iceland accepted the debit card from the booking. We booked an electric car because there was a special offer from SIXT. However, the staff of SIXT warned us of charging difficulties with electric vehicles at rental and offered us a complimentary switch to a gasoline-powered car. We declined the offer because we were was curious to learn more about electric vehicles. This choice was our mistake and resulted in 8+ hours spent at fast chargers and a route that needed to be planned according to charging stations. Getting full insurance paid off. On car return there was a big scratch in the car we had not to pay any surcharge. Still, the rental rate with insurance was more expensive than any rental car we booked before, but we did not find a better offer—the rule of supply and demand.
