I would highly recommend checking with your local DMV regarding smog issues unless this is strictly going to be an offroad toy. Also realize with a newer car and an older engine like a crate 350, you're going to require some wiring know-how, as all of the wiring harnesses in the car are meant...
I have owned a Commander for three years and love it. Beautiful leather, very trail capable, better than average ride for a jeep and the best bluetooth I've used in any car. WOuld highly recommend, but I'm not a hardcore off-roader and I imagine its no Wrangler in the dirt.
