My '93 5.2L has 204K also! Doesn't leak or burn any oil/fluids.
The P.O.s certainly didn't keep things clean in the ZJ, but from it's running condition, I'd say it was well maintained since it's major components are in such good mechanical/running condition, except the VC is spent in the T-case, but since that's not an item that can be maintained, there's no preventing that.
Going to swap the 249 for a 231 soon. I'm hoping that the ZJ's body and I both live long enough to see it at 300K.
The highest annual mileage on any vehicle I've owned was 8,176mi. Lowest, 2,054mi., so it's gonna take me a while....
