On the Mitsu/Dodge sites there are many references to bad trannies, both auto and manual I believe. I checked them out because I'd considered one of these before landing an SVX. Also, the engines in question for the base/better models are a single/double cam Mitsubishi 3.0 V-6. These engines are prone to burning oil once they reach a certain point. Apparently it's the valve guides. To check this out, start the car STONE COLD. If you see blue smoke at start up, it's already burning oil. This is a bout a $1,500 fix if it's got that problem.

Personally, I prefer a manual trans, but I believe there are people on one of the Mitsu sites that claim it grenades...
