I'll try to get it for you. However he did just tell me it's $50 over invoice PLUS 2k incentive...
Curiosity kicked in so I built it out.
2018 Expedition 4x4 with rear buckets, floor liners and cargo mat puts MSRP at $77900 and invoice at $74443. Add $50 to invoice and your at $74493.
Add HD trailer tow package and you are at MSRP of $79470 and invoice of $75935. If he's at $74500, they are probably doing $1500 in ford rebates in that number.
OK deal but you can do better. Ford cash is $1000, Ford finance is another $1000 so you should get $2000 in rebates easy if financing through ford. Own a ford and you get another $1000. Then there are $500 rebates for first responders, military, etc and I think another $500 for farmers.
You should target $73500 IMO rather than $74500. (more if you can qualify for more than $2k in ford rebates)
