My view:
My other views (in the way of general comment not aimed at anyone in particular) is that to get to know any vehicle properly you need to do as much of the repair and preparation work yourself. Doing this, as opposed to simply resorting to chequebook preparation by farming everything out to others, means you stand a better chance of being able to repair it yourself and not rely on other people.
Saying that you lack the time or knowledge to be able to do so does not cut it with me - you need to make the time and learn ...by actually 'doing' or at least trying to 'do'. Yes you will make mistakes, but that's just part of the learning process.
Buy a Land Rover (or other vehicle). Use it, fix it, improve it, modify it, get to know your vehicle - then think about taking it away. When you know what makes it tick surely you stand a much better chance of knowing what to do when something goes bang out in the middle of nowhere.
