I did many long trips in my brother`s in-law Grand Cherokee Loredo 2013. The same engine - it did almost 10l/100km on the motorway. My worse fuel consumption was around 16l/100km in Izu - 4 people in the car and language for two days. The tax is high - both due to the big engine and high weight of Gr Cherokee. The model you showed has air suspension. I would recommend any future buyer to research the reliability of that solution. The comfort is good, although for me at 170cm height the seats are too wide. I like to rest both of my elbows on motorway and can`t do it in Gr Ch. On lower trims, without air suspension, this is a great vehicle. Especially if someone needs AWD. I wish Toyota would pay more attention to this vehicle and learn few lessons ;)
