I just exchange my 2008 LR3 to the new LR4. It's a great improvement, never had any problem with the LR3 but, this one it's quicker and interior is very handsome. I know, the gas is kind of low but what do you want for a big truck. The ride is supple and secure, and that is the important thing for me.
Height, interiors, cameras, LCD screens to watch videos, the roominess and security.
A bigger gas thank will help a littler, I can't not complain.
