i have an 05 LR3 that i've had for 6 years now and have put about 85k miles on it. it has been a great truck, but it is somewhat "temperamental." we also have an '03 D2, which we are selling as we have a new 2012 wrangler on order. with the new engine/interior the wrangler is much more livable on a daily basis than it used to be. personally, i would consider the new wrangler rather than a used LR3. the new interior is just as nice if not nicer than the LR3's. it has the same HP now and slightly better MPG. it doesn't need premium gas. it also has a warranty. there is also an incredible aftermarket part selection for the jeep compared to almost nothing for the LR3. on another note, the LR3's air suspension is super comfy, but can be unreliable. either way, they are both fun trucks. they just serve a bit different purposes.
x2. I think you'd be well served by either.
