I recently did this with my 99 model that I've had for about a month now as a preventative measure. Very glad that I did as it was starting to build up sludge with only 61,000 miles on it. The car was a one owner Seattle car that was purchased from the original sale dealer. I didn't get much for service records so I figured it would be better to be safe rather than sorry. The thing I would like to add is that I found a way to ease putting the sump back onto the engine. I didn't have much luck with jacking the trans (manual) so I hooked a come along under the lip of the upper engine mount ( wishbone? ) and lifted it up approximately an inch or so and this gave enough clearance between the subframe to make replacement much easier. I'm not saying it made it easy but it went in without wiping out the bead of sealant which I would say is the main objective. Hopefully I didn't do any damage to the upper engine mount but it seems to be just fine without any excess engine movement and it shifts fine. I still used the pry bar between the crank end and the frame. Hopefully this will be of help to some one else.
