The LR2 is actually a pretty decent car. Seems to work well and be reasonably to own and operate. For the crossover sector, its a decent vehicle. Driving them is fine and MPG is somewhat reasonable. The big problem with these cars is for the price of a decked out one, you might as well buy the next size up rover. As mentioned before, no low range and not off road oriented. So if you plan on using it for anything more than a dirt road, it'll start lacking pretty quickly. But if you want a fancy crossover to run up the mountains in the winter, it is a strong contender. I like the new disco sport, its successor. Once again, a fancy crossover but if you get into snow or whatever, it'll hold its own.
The Discovery 2. LOL I hate to be a ************ but after owning an LR3, I have no idea why anyone would consider a D2. I love the ride and feel of the D2. But the LR3 is such a much better vehicle, might as well go for the gold. The LR3 has better suspension, better drivetrain, better interior room, better MPG, and better towing capacity. Its an amazing vehicle. If you think twice about it, consider how many 170-250k LR3s there are out there still running on their original engine. Now consider that D2s need a top end rebuild every 100k or so. Yep. There ya go. Of course you pay to play elsewhere but bushings and suspension compressor aren't as momentous as dealing with slipped liners.
The later LR you can afford, the better. I'd say bypass anything made before 2005. 07-09 seem to be very well regarded in build quality.
