Surely the way to look at this is what the car was like when it was made; ie new.
When any Land Rover is new (with the exception of the very old ones) it doesn't break down short a freak factory mistake.
So new Land Rovers should be judged on their style, capabilities, impact and so on. By those standards any Range Rover or Discovery scores highly. The L322 for example brought a modern take to the fabulously handsome P38's styling. The latest model has taken 21st century technology to a classic design to make the best standard off road vehicle available today.
But not all so... one took the great classic British nature of classic Land Rovers' engineering and styling, and threw it away, deciding that electronics could completely replace decent mechanics, and covering its chassis in footballer's wives' phlegm. And worst of all, its styling has managed to pollute the future of the P38's descendants.
The worst Land Rover is the Evoque.
