I may bash that Defender and LR in general, but I loved (love/hate actually) our Discovery. It was a cool vehicle, built like a tank so I felt comfortable with the fam in it. There were a lot of things to like. But, it still was under warranty when we bought it and I can't tell you how many times it left my house on a flatbed. When gas got to $4 it sat in the garage most of the time. Until on a trip into town it overheated and dropped a cylinder sleeve. The only way I would even consider buying another would be if it had pinned sleeves. And even then there are too much other choices that aren't going to be near the headache.
Anyway, if you're a gear head who enjoys working on his rides, or someone with enough disposable income then why not a Discovery. But I see a lot of people around here that are neither one of those driving them. Just some mook who found one on a lot and is like "look at me, driving a Rover". I'd be interested to see the Carfax on some of those Disco's and how many times they've traded hands.
