@J JOSE I have the 2017 JGC and the average FE is between 8.4 to 8.9 in city. On long drives I get over 10.5 kmpl.
If I were you I'd weigh my options and preferences carefully as this would be a long term investment. Since you only want a vehicle to use to office and back with no intentions to use it offroad and particular about the FE, why are you looking at a 4x4? You rather invest in a good sedan with all the features that you need and it may work out cheaper overall and give you a way better FE.
Back to the JGC, I have driven it almost 40k km in a year and have had absolutely no issues in terms of road usage or stability but if you do ever have issues, it is going to be more expensive to fix compared to your other options.
As a person who loves cars, I'd say don't only go with FE unless you are really driving a lot as in time you will regret it and will always have that voice inside you saying ' I should have gone with what I really wanted'. Speaking from experience here. 😥
