If you want reliability, get a newer TJ. After all a CJ will be at least 27 years old. If you want a classic and reliability, and you have a clean CJ to start with (not from the rust belt) spend some dough and do a body off restoration where you can replace worn parts and then dump in a newer FI, computer controlled motor/tranny combo. Then you will have a classic that will get you anywhere, anytime. And you will spend less than half the cost of a new ride. Keep your DD car for long trips.
