I wouldn't sell that TJ, but that is just me. I still have my 86 S-10 Blazer that was my first car and I haven't driven in years. I know I'll regret selling it if I ever did.
My plan from here on out is to make sure my wife has a good vehicle and I'll drive the beaters. Last year we bought a Tahoe as a nice vehicle for me to drive. When Hendrick bought it back from us because it was a POS we started looking for newer diesel trucks for me. Then we thought about how her car has 215k miles on it and how she really should have the reliable vehcle, not me. I bought a 98 3/4 ton Chevy and have no monthly payment for now, so whenever it is time for her to need a vehicle, she can get a nice newer one. If my truck goes down, I have two other registered cars I can drive. If my wife's car goes down, she really doesn't want to be driving a lifted 98 2500 Chevy, a 71 C10, or a 5-spd 89 Formula.
