Could I request invoice price plus destination minus holdback on an order?
Invoice (and MSRP) already include destination. You can get almost any price you want if you are willing to work hard enough for it. Getting "dealer cost" (invoice - holdback + tax/tags/registration) requires finding a dealer who is extra motivated to move a single unit, which will require you to continually follow up with multiple dealerships near the end of each month. Most people find it worth their time to just to let the dealer "win" and offer "dealer cost" plus whatever they think their time is worth.
Also remember to be clear that you want an "out-the-door" price including all taxes and dealer fees. Getting this number is like pulling teeth. Don't try to negotiate each item, just negotiate the final purchase price. Don't get hung up on if you are paying a bogus $699 "processing fee", as long as it is offset by a reduction in the vehicle price.
Have your financing lined up before you start negotiating. The real negotiating starts when you get in the F&I guys office. Just remember these words: "Thanks, but I'm not interested in that."
Nitrogen tire fill: "Thanks, but I'm not interested in that."
Etching: "Thanks, but I'm not interested in that."
Extended Warranty: "Thanks, but I'm not interested in that."
Paint Protection: "Thanks, but I'm not interested in that."
Hood Film: "Thanks, but I'm not interested in that."
Window Tint: "Thanks, but I'm not interested in that."
Anything else they offer to you: "Thanks, but I'm not interested in that."
Anything the F&I guy tries to sell you can usually be purchased for less from someone else after you get the vehicle.
Good luck!
