I don't understand the "cool factor" of no doors
Top down and doors off is as close as you can get to the "freedom" sensation of riding a motorcycle while remaining on 4 wheels IMHO.
So much of automotive effort these days seem to be insulating you from the experience of driving. And I get it... When I'm not in the Jeep, I want a quiet comfortable vehicle. With most vehicles, it's a mode of transportation and the goal is to get from point A to B, not to make the journey.
But certain cars it's about the journey. "Sporty cars" are about the journey. You don't necessarily want a car that's disconnected from driving--you want a car that gives you feedback from the road and is an immersive and exhilarating experience.
Riding a motorcycle is about the journey. Whether it's a sportbike, or a cruiser, or even a Goldwing, you are immersed in the experience.
A Jeep, with the top down and the doors off, makes you part of your environment. It's loud. It's windy. If it's below 75 degrees, it's COLD at highway speeds. But you're part of the experience. You're not hiding from the environment, you're experiencing it, for better or worse.
I don't know anything about the "cool factor". But I do know that the feeling with doors off is different than doors on. And it's a satisfying feeling that's hard to replicate otherwise.
