They can be serviced by a squaddy with a few days training, you should be able to manage. Bear in mind the Series are "field servicable". My own approach is to do my homework, there's loads of info, post on here, then eather do it my self or if its heavy (I'm 65) or takes 2 people I use a local mobile mechnic who likes working on old Land Rovers. Its not his speciality, in fact he was the only mobile mechnic in our area willing to work on old Land Rovers, the typical response was "I don't need to do that anymore" but he likes the simplicity and it is a change from modern vehicles. I just pay by the hour for as long as it takes.
