I've seen two types of invoice. One with a marketing fee and one without. I don't recall if the marketing was in the $500 range, but if it is that could be the difference.

 

Okay Thank you. What is the marketing fee for? I mean I am pretty sure alot people know what a Mustang is.

 

Here's an example of an invoice WITH the marketing/advertising line item (see bottom of Invoice). You can Google FDAF for more info.

 

The FDAF is their advertising fund, so it goes towards making their commercials and such. I was upset when I saw my final price bump up $500 from this but the dealer said they can't take it off because it is a corporate charge. I am getting mine under the X-plan though so I don't technically have my "final price" until the car comes in and see what incentives are available at that time and hopefully I can negotiate a little bit with the final price and financing.

 

What's the fuel fee? Are they charging you to fill it up? WTF

 

basically - make sure you tell them to fill with premium!
