rovers are notorious for breaking down....go to
http://www.landroverworld.org/forums/index.php
and ask away on there. There you will see many people asking how to solve problems they are having....when I was looking into getting one it seemed there were a lot of electrical problems, which is no fun. A land rover Defender however, is a BADASS offroad car. That and the Toyota LandCruiser FJ40....sweeettt.
