Had a great time renting from Sadcars. The car was old, don't get me wrong, but it ran great. Took us to Landmannalauger through rivers and over gravel roads with no worries. We didn't have to think about scratches or dents or worry about the engine making it. Having a new car may seem like a good idea until you get onto some of the harsh road conditions in Iceland. Sadcars maintains their cars well and is very helpful.
