To be completely honest, I don't think Ive seen one of either with over 100k. Both are great vehicles, but they are very different. It really comes down to what fits your lifestyle best. If you will be taking it off-road or need the extra space, definitely go for the LR3. On the other hand, if it is mainly for on-road driving and you don't need the room, you can save money or get a newer, lower mileage LR2.
