This all sounds like it was written by a dealer to mislead the uninformed so they can put more money in their pocket. If you can't get a new truck for at least 10% off sticker you have no deal. Invoice should be the starting point of your negotiation because the dealer is still making profit and holdback on that amount. With their volume discounts from the manufacturer it can mean several percentage points below invoice for them. Any time you see pieces on paper like shown here they are a prop and not a true reflection of what a dealer would actually receive for new cars delivered. The closer to the new model year the greater the discount. Last year Chevy and GMC had $18,000 off their remaining inventory and they still made a small amount of money on them or would not have sold them at that price. Don't believe everything you read. Especially from a dealer. Car dealers are like politicians. You know what you're getting when their lips are moving.
He's getting 7,400 off. That's almost 13%. So if your goal is to get 10% off, we've hit it.
Car dealers still exist and function to make money. But I also think that the internet has brought about a lot more price transparency.
If the advertised internet price is what they're actually selling it to you for, they're probably pretty honest. If they're advertising military rebates, FFA rebates, etc. in their bottom price--they're up to shenanigans.
All of that said, we're here discussing this because we're wanting to buy a truck. You can absolutely walk away over 1,000$. If it's the exact truck you want, I don't think 1,000$ makes sense to leave over. I spent a month looking for the exact trim, options, color, etc. The dealer price was 47,500. I wanted to be at 45,000, they would go to 46,300. You can absolutely tell them no deal. But the next dealer likely won't be substantially better. And if 50,000 gets me the exact truck I want, I'm not giving up some of my options--like the 33 gallon fuel tank and the 12 inch display which cost another 2,500$ so the next dealer can get me 1,000$ lower. If we're sitting here arguing about 55,000$ vs 49,000$, I think it makes a lot more sense.
