I am sure the new platform will bring a ton of refinement to the model(s). Other than in mid-high end vehicles this is something Chrysler/Dodge/Jeep has lacked for decades really. This refinement makes sense for the Dart and perhaps the Compass, but to me not the Pat.
I would be immensly disappointed to lose the Pat in it's current clothes and platform. I have liked it since the day they came out for it's efficiency, practicality yet urban/rugged style and utility. To replace it I would most likely be looking elsewhere as I do not like the compass, can't afford the GC and don't need the complete off-road capability that the Wrangler Unlimited offers (I have a fam. and need 4 doors).
I know we all know very little right now, but based on articles like this, spy pictures like this, the fact you don't see advertising for the Patriot anywhere anymore (all Compass) and the overlap of the Pat/Compass, the deletion of this model seems likely.
The don't build cars to sell to me...would not make sense as I keep them for 8-10 years anyways, they build them for the masses.
