Welcome to CEG. I think you'll find the forum to be a useful source of information.
One item you should check on, if you haven't read this already: The water pump on V6 models uses a plastic impeller that's noted for causing problems. Use the "search" capability to learn more about this issue.
I changed the pump on my '95 myself at about 55K miles; it was still in good shape, but I'd read enough about others' problems that I changed it purely as a preventive measure.
Enjoy driving your Mystique!
