I can't waste time to read comments before, so sorry if I suggest something already suggested.
Most comments are about diesels, but since I live in europe we have all your line up with diesels, so I can comment more on what improvements in these diesels I'd like to see- they work great, and have decent power, but I believe you should work more on biofuel capability. Biodiesel is the nearest future, and remember that many of us buy jeeps to use them 10-15 years. I'd love to buy a biodiesel jeep to be able to run biodiesel when regular diesel prices will be much worse than now.
As for other improvements, I think I'd like to see some simple additions that would help offroad, like swaybar disconnect on WK (just like the one in JK Rubi).
My last suggestion for now is strictly marketing one- how about making trail-rated badge stages? I mean like 3 stages for increasing capability. For example 3 for Rubicons (hope to see WK rubi in the future
), 2 for jeeps with lockers etc, one for regular, capable SUV's like new Liberty. And give precise numbers, what does it mean- how deep it can waterford etc. I know there has to be warranty disclaimer and blah blah blah, but after warranty I'd like to know that my jeep is factory ready "for this and no more".
PS. Anyway guys you are doing great job so far, especially with giving world the JK rubi (one of the last truly capable stock 4x4), so keep it that way
