Mrs. riverdawg’s Park Avenue (with the 3800 V-6) is supercharged - no problems whatsoever with it in 80K miles, and she has a lead foot on the gas pedal! On the other hand, Mitsubishi’s supercharger was trouble-prone from the beginning. The reliability of superchargers, like many parts, varies greatly across manufacturers.
Wait till you get to 100K. Supercharger rebuild time, according to the guys with the Park Avenue Ultras.
Mitsu uses turbochargers, not superchargers.
