Stay away from 07-09. Those would mysteriously burn to the ground. This was a world wide issue. By the time they got to 2018, most people complained about the steering. The issue with the steering is its a solid front axle with a gear box. People expect it to handle like a sports car for some reason. The rest of the common complaints were about fit and finish, some body weld issues and a few electrical issues.
The V6 isn't too bad considering they tried to build a commuter SUV out of a Wrangler. If I was going to get one, it would be a 4dr, V6, Auto Rubicon. To me the 2dr is too small. Three of the guys I wheel with own 4dr Wranglers and its a squeeze for gear. I sat in the back seat of one for a few hours and it wasn't too bad.
Over all, its a Jeep. Fun, a crap load of mods available, poor fuel milage, poor road manners.
In my area, a 40k mile Wrangler is going for 25k-37k with the Rubicon's going for around 40k.
