I assume it has the automatic transmission? If serviced, the engine and transmission should be just fine. 190k and I imagine it'll have the common lifter tick (my 2000 TJ has had it since I bought it at 53k miles) and there may be some minor maintenance issues here and there. ie.) Water pump, radiator, TPS etc. but nothing foreseeably major at 190k that is a commonality among the 4.0s going kaput.
Granted this is all speculation. Without seeing the condition of the Jeep in question or it's service history, all of the above in this thread myself included, is moot.
