Diana was ready to make her deal and buy a new Hyundai Elantra today. We did our homework and figured out what her trade was worth, as well as the real price and invoice on the new car. Diana ran the numbers for her budget, and I agreed to be the asshole negotiator.
We picked a good day for it. They had not sold a single car all day, which isn't surprising given the crappy weather. We were the only people in the dealership as well. Bottom line, we were the last chance for them to sell anything.
There isn't a lot of markup in the car, so we were OK with a price close to what people were generally paying, like $200 over invoice. But the absolute bottom for her car was $6k, and not a dime less. Part of the reason for that is she wanted to get her payment down around $200, which was easy enough given Hyundai's 2.9% financing. The data is all on the Internet.
We laughed off the first offer for the trade, which was $4,000. He even printed out the Blue Book evaluation, which was a grand lower than what we found on Edmunds. I countered his $4k with $7k, then said we'd concede to $6,500. He looked up some more shit online, and said he'd "reluctantly" give Diana $6k. Deal. That's what our target was. We essentially got exactly the deal we wanted.
Car sales just suck. Even the Saturn no negotiation scheme is bullshit, because on inexpensive commodity cars, there's no markup. The margin is in the trade, so you have to be a dick about it. I'm sure it comes as a shock that I don't mind being that dick when it comes to buying a car.
