It is hard to do much in Iceland, outside of Reykjavik, without renting a car. We went in April and wanted a vehicle that could handle snow and rougher terrain, so we chose a Subaru Forrester. It was raining when we arrived and the car lot was not covered, so it was hard to do a quality vehicle inspection before signing a paper saying that the car looked ok. I had noticed two small chips in the window later on in our trip, which I am still not entirely certain were not there when we picked the car up, and the rental car company gave us a bill for nearly $400 dollars for repairs. There is not much opportunity to investigate when you need to catch a flight and I think they know this. Luckily, the credit card we used to book the car had a good insurance policy but it took a lot of back and forth to get the required paperwork for reimbursement. The funny thing is, the rental car company sent me a picture of the car as I supposedly turned it in with a crack running the length of the window. It was a good thing I took pictures to prove my innocence.
