Another option with the gas vs diesel is the available unlimited mileage/age bumper to bumper warranty you can get thru Chrysler. It's available on any new or under 4 year old/48k miles Dodge/Chrysler/Jeep rig. As long as the repair doesn't go over the blue book its covered. If you keep vehicles a long time it's definitely nice. Only downside is you can't get it for diesels or fleet vehicles.
