I bought my 3.7 L Nitro new and I love it. I am a contractor and this is my work truck! I've pulled a 6'x 12' cargo trailer every day for the last year and a half and this truck hasn't let me down. I've had the driver side interior door handle break and had a couple of recalls taken care of, but with 69,000 miles I've never had a major issue.
Bluetooth stereo, great 4x4 in the snow, excellent sound system
fuel mileage, stronger door handles, ability to turn off the ESP "completely" (it nearly put me in the ditch while trying to drift a corner on a gravel road!)
