90% of the games begin when you finance the vehicle at the dealership. Don't want to put $2000 down? Let's just add another year to the term. Or how about we add $50 / month to the payment? I watched in shock as salesmen would come back with increasingly worse offers in terms of total cost and customers would leave happy thinking they were great negotiators.
Americans are shockingly bad at math.
It's good to research what the invoice price is, but this isn't their actual cost. Manufacturers offer incentives to dealerships based on all sorts of things, including hitting certain sales goals. These rebates aren't factored into the invoice price, so even buying at invoice isn't always an amazing deal. My understanding is that the rebates/incentives are bigger with some manufacturers than others, but I don't know the details.

With the two new cars I have bought so far I paid substantially under invoice both times. Seems a made up number to me.
I also paid cash each time and they begged me to finance for three months so they would get more incentives from the manufacturer.
So, some legwork with a throwaway email address, but still very sofa compatibile.
