I use a car buying service from USAA (which now uses True Car), they don't have all of the options built in currently but they are showing the Fusion Sport with no options getting $1,586 off MSRP for a total of $32,764 (including destination, regional fees, and a $500 incentive).
I recently showed my brother the discount I would get using the car buying service for various cars a few months ago and he was shocked - he had fleet dealer at Ford that was giving him a price of $500 over invoice on a 2016 Mustang GT, he went back and told them the True Car deal and the fleet dealer told him that they honor True Car at $900 under invoice.
