Based off a Mercedes platform. Mercedes suspension. Mercedes transmission. And some more stuff. Almost effectively a cheap Mercedes with a HEMI. Do remember that Mercedes did own Chrysler for a while, so got a lot of Mercedes stuff. 3.0L Diesel was Mercedes. Current Grand Cherokee shares a Mercedes platform. 5-Speeds are Mercedes. Chrysler Crossfire is straight up Mercedes. Plus a lot of the other smaller components that make a vehicle come from a Mercedes parts bin. Chrysler has always had good/bad *cough*Mercedes*cough* relationships with other companies. AMC basically helped make Jeep what it became. Mitsubishi and Chrysler shared a sh/t ton of stuff during the 90's. The current I4 is Dodge, Hyundai, Kia designed of which Mitsubishi uses as well. Compass/Patriot share a similar platform for the Mitsu Lancer/Evo. Dodge, BMW and GM worked together on that Hybrid transmission. And now Chrysler is owned by FIAT, so is going to get a lot of FIAT technology, components and platforms.
