Your kids will grow up, move out, and you and your wife can go on TJ adventures, and you'll be able to DD every day. While a 4 door SUV or minivan has its place with your family dynamic, they can become soul sucking machines, so keeping the TJ around helps fill the tank, so to speak. you know what I'm saying.
That’s one of the things I think about. Once they are all grown up and on their own, the TJ will get even more use than it does (right now it’s mostly weekends we drive it on).
Since the TJ is all paid off and almost done in terms of mods, it basically doesn’t take any money other than gas. That being said, I didn’t want to go down that route of “building” another Wrangler. It’s so damn spendy!
