Invoice is not sticker nor MRSP. Invoice is invoice.
Don't put a deadline on buying a car unless you NEED this car for some reason. A car is not a small purchase and one of the only items you can actually negotiate for a better deal, so you want to make sure you shop around because not all dealers are equal.
Its the end of the year, wait until the last week when they are trying to hit EOM and EOY numbers. More likely to get a favorable deal.
Invoice is $34,890 found here http://www.car-buying-strategies.com/dealer-invoice/ford-mustang-prices.html
Thats what he should pay. Invoice OTD. Eat into that hold back. I did it with no plans or rebates about 1-2 months after the order banks opened up. I also went in with the pdf sheet from here with what invoice is for each car with with whatever option you picked. They were a bit shocked and asked where i got the sheet. I explained that it didnt matter. If they wanted a sale that i was paying invoice OTD or i was walking. I didnt care about free this or that, that they would try and offer to justify not coming down. I got my custom ordered car exactly how i wanted it. It didnt sit on the lot, it wasnt removed of any of its plastic, it wasnt driven by some asshole porter that would also end up taking his grit loaded wash mitt all over the fresh paint, it didn't sit in any rain. It was glorious
Note that this method is not likely to always work or even work half the time if at all because what you are saying here is the dealer takes a $1000+ hit to sell you a car. Assuming tax is around $2-2500, and holdback is only $1100, they are taking a $900-1400 hit after tax by selling you at invoice OTD. I think invoice PLUS tax is a reasonable price. I think MSRP OTD is what you should be aiming for.
Im nearly 50 and its worked every time for me. Ive bought dozens of new cars over the years. The dealer still makes money. Screw their wallet. They make better money if they sell by sheer volume, if you believe they dont someone lied to you. They arent in the buisness of handing out cars at a loss. Do you really believe the car sales manager wouldnt get fired for that? If the dealer isnt a volume dealer i dont buy from them. Its as simple as that.
Correct. Dont buy from non volume dealers. Why pay more? Even if someone has none of those dealers in town its worth a couple hour drive to save thousands.
