in my mind I think it's obvious that the Compass, the Patriot, and Commander were attempts to pull non-offroad people to the brand, and expand the Jeep brand further than it should.
I'm not a fan of the Compass or the Patriot, an Anemic little car with a Jeep badge that wouldn't make it up some of my friends driveways. But I really don't understand why Jeep made two of them. basically the same vehicle with a few different angles on the body.
The Commander, I have seen on the trail. And with some moderate upgrades lift, tires, and gears, it can be a pretty cushy trail rig.
I don't think it was meant to compete with the Hummer. The H1 was already dead, the H2 sucks off-road without $40,000 in upgrades, The H3 is more for competing with the lower end SUVs. The Commander in my opinion was built to compete with land rover/range rover, and the more High end Luxury SUVs. The vehicle that the Grand has tried to Compete with, but has never been completely successful. But the flaw here is that the Commander now competes against the Grand.
As far as bringing the XJ back. That will never happen, no matter how many people(myself included) scream for it. Course you could go buy the new chinese version.
