Glad to hear it's working well. It was a bit earlier than that the Mitsubishi engines were troublesome in Chryslers. Their 4 cyl in the 80s burned oil too soon. Chrysler replaced it with their own very successful 2.2L and 2.5L engines, which we had. The Mitsubishi 3.0L V6 was a reliable engine from friends reports, but the Chrysler 3.3L was better from all aspects. Glad to hear Mitsubishi solved their problems.
Great engine in our 2001 Sebring, but I hear there were problems in the early years of that engine, as is often the case. Wasn't '98 the first year for that engine?
My suggestion is not to buy a significant new mechanical design like an engine or transmission for about two model years.
I have experienced grief when I unknowingly bought to soon a new design. I could give you a real tale of grief I had with the Chrysler 4 sp manual transmission in my '81 Horizion. Thank goodness Chrysler replaced that transmission completely with success in the 3 rd. year, but the time I wasted up to that time was ugly. If I had the money I would have dumped it very soon.
