This the cheap and easy option to reach the west-fjords. Alternatively you can expose yourself to an expensive airplane ticket or 150 km or so gravel roads. At 20 euro per person and the same for a car, I thought it was reasonable. It takes the little ferry 3 hours including a short stop at the island of flatey. The small-ish ferry can take20 cars but you have to reserve. If you make a stop a flatey the crew puts your car in the docks at breidafjordur as only passengers can get of at Flatey.
