If selling masses of cars we would not buy...
If a diesel option were to become available, I'd most definitely consider buying this and I might consider it in gas if I were to be able to fit comfortably and we were in a position to retire the LJ from DD status.
This would make a great option to head down/back to our office in Cincinnati over putting miles on the LJ and should blow away the highway mileage we could get with the JK.
If MOPAR is smart, a very nice roof rack/cargo box option is in the works for this to allow extra storage for longer trips. If I were on the MOPAR team, I'd also be looking at ways to get a motorcycle-sized trailer behind this with matching paint and tires/rims for the same reason. I'd have them sitting on the dealer lots ready to slap on a trailer hitch ball. I think they'd sell a boatload of them for folks who only really use all the space in an SUV/minivan for longer trips. That pretty well defines our use of our JK.
Nothing saying that same trailer wouldn't work nicely behind JKs either.
