My understanding on a typical $20-30K car, probably about 3-5%. Not including the kickbacks from the manufacturer that never show up on the invoice on the car.
I know one PO in my old congo who was a used car salesman..and he was a shady character in my opinion in more ways than one. Sold me (or pointed me to) several cars over the years..all ended up lemons...after the last one (3rd or 4th) I finally got wise and found my own car.
here is my only story about buying a new car from a dealer.
When I bought a new car in 02, I bought a Honda. I had researched car prices for 2 year leading to that point. When I was ready to buy, I went on Consumer Reports and ordered a couple of new car reports...those reports included wholesale cost, rebates, etc...and what sort of profit margin the dealer should reasonably expect to make.
So I had a price range in mind for two specific cars at the Honda dealership. I went in on a Saturday. I told the salesman that I was prepared to buy but only within certain price ranges. He was salivating. I took the car on a test drive..about 15 miles as I remembered...got back, he wanted to negotiate, asked me to shoot him a price. I told him up front I had the reports and done my research. He tried to get me to give a price. I told him: "Look, if you shoot me a price within the narrow range of reasonable profit that I have on this report, I will buy the car, no question." He started to try that go talk to the manager stuff. I said, "Joe, how long have you worked here?" He shot me an experienced number of years. I then said, "You know exactly how much you can sell me this car for and still give yourself a nice commission and the dealership a profit. You dont need to talk to a manager."
After a brief argument about the $95 floor mats that were the only add on listed...and several feeble attempts at trying to upsell me on unnecessary things (rustproofing...which I said, "if the car comes out of the factory and then needs additional rustproofing, I may need to rethink the whole buying Japanese") ...the guy shot me a price...it was on the mid-high end of my range. I have no patience for playing the game and since he shot me a price in my range, I accepted. I got that in writing then discussed financing. I got financing (with great credit scores the terms were very favorable) and a car in less than 5 hours on a Saturday afternoon. I left my junker on the back lot for about 3 days until I could sell it (an old 79 Caprice) to a brother for parts..he brought his racing trailer...ever try to fit a Caprice into a racing trailer? He had to crawl out the car window and out the side panel of the trailer.
I dont play with these folks. Most expensive purchase of my life....I walk in and take control. I still have the car 6+ years later..189K miles.... except for rebuilding a transmission (which was probably my fault for not having it serviced it correctly), it has all been normal wear and tear and maintenance. No regrets. Same sales guy is still there ..I see him when I have some service work done.
