I saw one (RRS HSE) in the flesh last weekend and I really liked it. The luxury package included some really excellent seats with soft leather and nice matte-finished wood trim. I wish the LR3 had both! The RRS also comes with far superior tires (Goodyear's on the LR3 SUCK)
For me, the boot wasn't big enough for my dogs, so the RRS would be out of the question. But I liked the interior better, and the styling is no contest IMO (RRS).
The only real fly in the ointment (assuming you don't need the cargo space) is the ride height. I am going to take a tape measure over there this weekend and have a go--Land Rover's publishe specs make me believe it may have been "lowered" or at least not raise as high.
