Slightly o/t and I hope I don't get flamed for saying this, but if you ever wanted to become more mechanically minded then a Land Rover is about the best place to start... everything is so.. straightforward... well with the early ones, anyway. Unless you are allergic to oil, anyone with some basic tools and a Haynes manual can wield a spanner well enough to do the basics, and it's surprising how quick you build a bit of confidence. Some jobs needs proper professional help, for sure, but a lot of jobs are expensive not because they're hard but more because they're time consuming... taking stuff off just to get at the bit that needs fixing... etc.
So take this forum's advice and buy a good one to start with... but don't be scared of getting a bit dirty with it, so to speak. A Landy ain't really yours until it's claimed some of your blood and skin.
