Re: why no summits
I felt that the Limited was in the sweet spot of features and cost. The Overland had more upscale options but not much in the way of added capabilities or must haves.
The Summit really is outfitted to be a luxury SUV which means that it has to compete with BMW, Lexus, Range Rover, etc. Plus, Jeep is at a disadvantage in the luxury market in North America as it's not seen as a Luxury brand. Traditionally Jeep's image is as a workhorse and off-road go everywhere vehicle.
