What city are you in? In my experience, dealers weren't willing to discount the factory orders much more than 500 to 1000 off invoice before rebates. I shopped around a 250 miles from my area so was able to find someone who was able to discount enough for me to move forward. If an equivalent car was available at an aggressive dealer lot in the area, I could have probably saved another 500-1000 but nothing close to what I wanted was out there so I went with factory.
Northern CA, and it's been a very frustrating process once we decided to go with the Hybrid over the Odyssey. Half the dealers here don't even have 2019s in stock, so we decided to look at 2018s. My local dealer found one 2018 that was perfect but when he went to transfer it, the hybrid battery was dead and the factory wouldn't give an estimate on when the new one would be delivered. A few other 2018s are so old they are subject to the recall (which means manufactured before March 2018). One of those was fixed but we decided we don't want an old, unused HV battery.
With 2018 eliminated from consideration, I used the Chrysler website to search for inventory in all of California, Nevada, Oregon and Washington (changing my zip code to get around the 125 mile limit). I found exactly one 2019 Hybrid Limited I would consider buying (because we refuse to buy hot-as-**** black or deep mocha seats, even if they look nice), and that dealer showed no interest in moving off MSRP.
That meant we have to turn to factory order. The local places all refused to budge of MSRP. One claimed they make a $100 profit on hybrids (which would be true only if MSRP - invoice was the actual and only source of profit). I tried South County, which offers deep discounts on 2018's if you want fancy-looking-burn-your-arse-off black seats, but those deals are to cut losses by moving old inventory, and they didn't offer a discount on a factory order 2019. I'm slowly expanding my circle because I'm not really in a rush, but it's starting to look like I might buy an Odyssey over Memorial Day.
