I certainly feel your pain - i was told by my dealer when i ordered that it would take 5 weeks - 6 max from order to delivery. I can tell from current data available on MOTS for Cherokee deliveries in 2014, total time from order through dealer delivery is averaging 56 days (out of 24 deliveries) - average of 8 weeks.
Had I been told special order delivery would take 7-9 weeks I might have made a different choice (take from available inventory), especially since I've been renting a car the last 4 weeks.
Since were both on week 7 of our ordering process, I'm guessing we too will have our Cherokees soon...
Getting back to your original point, I don't think you will have much luck on getting the delivery fee eliminated/discounted - Worth a shot though
