My opinion is to buy it . The late LR4 are the last of the good Land Rovers . Chassis , engine sorted and quirks fixed .
Forget the possible new Defender . All they make are crap street cars now . You've got a bird in the bush ....................
I know we've been picking on the new Defender, but it appears, at worst, it's going to be what the Discovery 5 should have been, and a better vehicle than the LR4. In other words, if you think the LR4 is a "good" Land Rover, you'll have no reason to believe the new Defender isn't a "good" Land Rover, and probably a "better" Land Rover.
