I used TrueCar.com for a starting point and negotiated down from there. You can use Edmunds or Kelly Blue Book too as all 3 will be close in price. Don't be in a rush, be willing to walk away and go to another dealer. Dealer invoice is just a number, the dealer generally pays less and the higher their volume the less they pay. The dealer also gets a kickback from the manufacturer (it's called holdback) so even is they sell it to you at their so called cost, they still make money. Make a list of what you need, what you really want and what would be just nice to have. Do you really need the power sun roof, the rear fold and tumble captian's chairs, the rear DVD entertainment system, the technology group or the leather seats? If you don't want it or care about it, don't let the dealer force it on you. So you should be able get a a nice R/T, 5.7 V8, AWD, towing package, 8.4A radio for $41K to $41.5K plus tax and garbage fees. (Maybe even less if your persistent like me.) This would be something that lists for $44.5K. Just because the dealer doesn't have it in stock doesn't mean that can't get it. They can search it out at other dealers, just like you can on-line too. On the Dodge web site use the Build Your own option to configure what you want then do a search expanding the distance to 200 miles, if you find what you want of very close, print it out and take it with you. Same thing with any on-line pricing you find. Don't get conned into dealer add on's like paint sealant, extended warranty, etc... Pretty much everything outside of license fees and taxes is negotiable. If you gave a good credit rating you should be able to get a loan for 2.24% @ PNC Bank or 2.14% @ Chase on 60 month loans. Maybe even as low as 1.99%. You don't have to finance through the dealer, but they should be able to match what every else you can get. If your a credit union member check their rates too.
Were paying $615/month for 48 months on a 2015 SXT Plus. $39.6K MSRP and we got it for $35.7K. That's about $1K under dealer invoice. The only thing we didn't get that we wanted was a CD/DVD player. But I RIPPED the CD's and put them on a USB thumb drive.
