The Mitsubishi Endeavor mid size SUV debuted late in 2004 and introduced style to the somewhat boxy and dull designed SUV's available on the market. Exaggerated wheel flares and a bold front end design quickly distinguished this SUV from the others. The 3.8 liter, V6 engine was capable of 215 horsepower and would tow up to 3500 lbs. and a fully independent suspension provided a smooth and well controlled ride. Three models were available-the LS, XLS and the Limited, all featuring good acceleration and a 4 speed automatic transmission. The second row of seats in each model folded down to accommodate up to 76 cubic feet of cargo, which was not as roomy as some other SUV's on the market, but satisfied those who were willing to sacrifice a little bit of room for the distinctively different and appealing design. All models were also available with all wheel drive or front wheel drive.

For the 2005 model year, changes were minor but included standard side airbags on all models and a standard anti theft system for the XLS model. In 2006, the XLS model was discontinued due to lagging sales, but the LS and Limited were upgraded to include traction control and anti lock brakes as part of the standard package.

The 2007 Mitsubishi Endeavor received minor changes including a new SE trim level that includes heated leather seats and satellite radio. In addition to the previous discontinuation of the XLS model, the Limited was also dropped from the lineup, leaving only the SE and LS models. This was a strategic move on behalf of Mitsubishi to accommodate the perceived desires of consumers and provide a more comfortable and luxurious mid size SUV with higher quality materials as opposed to a transportation powerhouse with multiple seating and cargo configurations. A long list of comfort and convenience features in addition to ample room for 5 make a ride in the Endeavor a very pleasurable one.
