Plenty of adults, including my 6foot+ kid, often climbed in and out of the back seat of my 2-door Dodge Dakota. And the 2-door Bronco has tons bigger doors than my Dakota had, so it should be fine.Like I said I got inside and back out, with my large size. Really no different than getting in and out of ANY other 2door, the only difference is it sits higher than most 2 doors Younger more nimble persons will get in and out fairly easily.
Much easier than my "69","74",and "77" my "66" was the 2 seat Pickup
Plus, it forces people to learn the importance of calling "shotgun!"
When you mention the 69, 74, and 77, you are talking Broncos, right?
