Not sure about the Cummins, but I think I know where you're going with this. The VM diesel was a real turn off when we were considering a GC equipped with it. There has to be a better choice for a diesel engine than the 3.0L VM diesel they offer it with. Flame suit on.
I love diesel engines, but I wouldn't want a diesel anything in a new vehicle. The ridiculously expensive emissions control systems have made diesel a stupid option at this point for anyone who doesn't do constant heavy towing.
