I know Rovers are well known for having reliability issues, but I may be taking possession of a hand-me-down LR3 and I want to see what of it's known problems can be (reasonably) addressed by replacing certain components. My understanding is that most of Rover's issues tend to be electrical gremlins, and I already have plans to swap out the glitchy air suspension with a fixed coilover setup, which would remove one big problem area from the equation altogether. What else should I consider doing to it, and what else should I look out for?
