Do you need the offroad and/or ruggedness advantages of a body on frame vehicle? Honestly, the current Jeep Grand Cherokee is a beautiful car and way more comfortable for highway driving than the 4Runner; main concern there would be longevity and reliability.
We have two Grand Cherokees a 2004 with over 240k miles and a 2014 with 330k. I am looking to replace the 2014 with much more reliable vehicle.
JGC's are perfect balance between comfort, off-road utility and MPG. However Jeeps reliability has dropped below Range Rover.
If Jeep still had Lifetime warranty I would buy again, but without it, no way. Chrysler kept my 2014 on road for 330k miles under warranty which I very much appreciate but I had a lot of issues. Now tranny shot (not there their fault, it lasted over 330k miles) and they are buying me out of my lifetime warranty so I will take buyout and buy new brand.
I was very fortunate to have lifetime warranty or I would have sold 2014 years ago. 2004 is differtent story.
I don't drive much off road but I like to have capable vehicle when I do. My off-road is mild also.
