Some of the early Rincons had cam issues, and the 03-05 had drum brakes.
That said, with low miles and hours, if the price is right grab it.
You can upgrade to disc brakes by simply swapping 06-current Rincon, 05-11 Foreman, or 05-14 Rubicon knuckles, calipers, and rotors onto your bike.
If you have cam issues, put a new cam in.
Other than those minor things, they are good bikes.
