, it all depends on if you'll use the QL or not. 95-98% of my miles are on road, and for the rest I do like to explore off-road. To date, with approx 25,000 miles on my JGC, I've got about 300 miles off-road. As a rough data point.
I use California's off-road parks with marked trails to learn and train on what the JGC can do, and the OR-1 and OR-2 comes in very handy. A stock JGC can handle some tricky obstacles on occassional use with the QL. Taking what I've learned in those controlled conditions, I am more confident to explore off-road when on a road trip out in the middle of BFE.
If you will do a lot of off-roading then QL is probably not for you. Go without and lift it. But for occasional off-roading, I recommend it. If you consider it, then on your test drives lift up to OR-1 and 2 and go over bumps. You'll want to hear and feel the normal THUMP!!
in OR-2 before you buy.
My QL in my 2014 has been trouble free. So far. (knocking on wood as I type this) Oh and I am in this JGC for the long haul. I want 300,000+ out of it. My last car was a 2001 Honda CR-V that I also bought new and put 225,000 before selling to my son. And I took that off-road exploring too. But it was very limited there, of course.
Good luck and please let us know what you decide and if you buy or not. Data points for us here, too.
