This is false. The down payment, by definition, fundamentally goes to reducing the value of the loan.I also have an issue with down payments because oftentimes the money just goes to the vultures at the dealership.
The money didn't go to those vultures; you agreed to pay a price that was $3000 more than was necessary. Had you negotiated a price $3000 less you would still have given them your $1000 but you would have had a better deal on the car.
As I posted earlier and Lindley posts above, you need to figure out what the invoice price of the car is before negotiating with the dealer. Never take their word for it based on a sticker written on a window; that price is negotiable. And never be afraid to play multiple dealers off each other. If Dealer A tells you they want X+$3000, tell them to eff off because Dealer B will give it to you for X. Dealer A will either tell you to eff off, or will give you a counter-offer.It wasn't until later that I realized some other Toyota dealerships offered the very same car for $3,000 less. Ouch. Had I gone to a different dealer, I probably wouldn't have ended up with the negative equity now.
