Being good off-road isn't, for me, the only thing though, that brought me into Landrovers. Reason I have a Disco is that we also need to use it to tow long distances on-road too, sometimes a caravan, trailer and sometimes horse boxes etc etc so comfort is an issue.
Most of the adaptations I've done are to make it more reliable offroad, steering and diffguards, removable towbar, but things like the HD springs make it also still well-suited to on-road. Removing the cat exhaust and centre silencer, egr valve etc also (IMHO) make it more reliable as there's less to screw up or get caught up when off-roading.
It's also a damn sight more comfy than and Defender, stereo you can hear, cb you can hear, decent seats, all help me to go off-road 'cos when the wife's comfy, she's happy ...
OK, our old series was also decent off-road but with a 50/55 mph top-end (reasonable noise levels) and 16 mpg ish it was unfeasible for what we needed. I'd have a Series or a Defender again, but it would have to be a second car to the Disco, and kept as an indulgence, but we can't afford that luxury at the mo'.
Actually I'd love a decent Series again ...
Actually I'd love a nackered old Series to do up again ...
