I have an 07 LR3, 50k+ miles and 0 problems, average so far is 15/16 mpg with about 80% city driving(it's my daily driver). Family trips are great, the LR3 is extremely comfortable, even the third row seats, space for gear is incredible, I just came back from a 5 day trip with 4 adults and 2 children, that meant I had to use one of the third row seats, and there was plenty of room for all of our stuff(I wish I had taken a picture). On the hwy the LR3 is very comfy, smooth and quiet, there were no complaints from anyone inside the truck during a 3 hour non stop drive. I've have done very mild, very easy offroading(thanks to sunny, flat Florida), and the truck is a champ, certainly much more capable than its driver, it leaves a lot of people in awe and disbelief when they see the truck gliding through mud and slippery terrain.
If you can afford the LR3 go for it, you won't be disappointed. I'm seriously considering buying a second one for the wife.
