I'm not sure what you mean by '"their" invoice,' but $545 is the Destination Charge/Delivery Charge, which is legit. "Dealer processing fee" is b.s. for what is also known as "I'm-gonna-make-up-some-name-of-a-nonexistent-fee-so-I-can-charge-you-some-more fee."Well, in addition to five hundred dollars over "their" invoice, they also have some close to two hundred charge called "dealer processing fee". That all adds up, that's for sure.
