That doesn't means they have to like the dealer model, but there are real advantages to it.
For years, I was aware of the cracks about "stealerships" and I didn't pay much attention, because I figured you get what you pay for and hadn't found a good independent mechanic. But I happened to see a help wanted ad for dealer advisors that mentioned commissions, about the same time as I had paid for an expensive repair on an out-of-warranty vehicle after dragging my feet quite a bit.
Maybe this is naive, but I genuinely did not know about the conflict of interest, and I expected the half of the dealer that sold (used) luxury vehicles to be no more predatory than the half that sells regular cars. On purchase, I figured, meh, I can afford the repairs, but I didn't count on paying for ones I didn't need and having ones I did ignored.
There are conflicts of interest everywhere in this process, as you might imagine.
But most dealerships are set up with a "service bay" that's just the desks of the service reps and a couple of parking spots, then after you leave they drive the cars around back to the actual service department. There's total isolation between the customers and the people doing the work. I suspect they might consider this a feature, "white glove service" or something, but it's irritating when you e.g. bring something in for diagnostics, and then get the diagnostic report from someone who doesn't understand half of it - an experience I have had repeatedly taking my lemon of a Nissan to the Nissan dealership because no one else in town has the stupid Nissan proprietary diagnostic computer.
Seriously, when I brought it in to have them figure out a problem that had been frustrating me for a while (I do most of the work on my cars myself), they confirmed my suspicion that it was the fuel pump and maybe saved me the work of replacing the fuel pump when it wasn't the problem. But, the service advisor also told me they recommended replacing the entire steering rack (!). When I asked why, he seriously struggled to come up with an answer, and just said something about it being worn. Really? the quoted rate on the replacement was more than the car was worth, and he didn't even know why they were recommending it.
Now I think I need a stability control reset that as far as I can tell only the dealership can do. I've really been avoiding bringing it in as I know they're going to charge me at least their $170 diagnostic rate and probably write me a quote for over $8k in work again, all for something that apparently takes about 30 seconds if you happen to have a Nissan CONSULT II.
At the same time, I've had no problem asking to go directly into the shop and talking to mechanic while pointing at the part in question.
So I conclude, as everyone says, you got to do your own work as much as possible on an out of warranty European car.
One reason I didn't realize this is because I used to drive a pretty mundane vehicle under warranty, so they never recommended anything grossly unnecessary.
Basically all of those things died with the rise of the internet, because you then have direct access to the manufacturer via their website and could order parts and have them shipped to you. It would also be a lot easier to find a local mechanic if the manufacturers would publish the service documentation for their vehicles on their websites, which they don't do primarily to placate the dealerships who don't want the competition.
It's almost surprising that you can't buy cars on Amazon yet. You can buy cars on eBay, although presumably not direct from the manufacturer as a result of the nonsense dealership laws.
(which is some sort of regulatory problem probably, the point is that it is the status quo for there to be a dealership oligopoly in many areas)
It's not really super convenient to get service 60 miles away.
Worse, Tesla is effectively a a national monopoly. And that's far worse, because it has no competition for sales of Tesla vehicles or service.
The manufacturer might like to claim the entire savings, but there are two reasons that typically wouldn't happen.
First, then the manufacturer's margins are higher, which changes the calculation of how much margin to sacrifice to increase sales volume. If before the manufacturer was making $2000/car and the dealer was making $2000/car then the manufacturer lowering the price by $1500/car to double their sales isn't profitable; double $500 isn't more than $2000. If the manufacturer is now making $4000/car by cutting out the dealership, lowering the price by $1500/car to double their sales is worth it; double $2500 is more than $4000.
And then second, because the competing manufacturers would have the same incentives under the same circumstances. If they lower their prices by $1500 to double their sales, that's coming at your expense if you don't do the same.
According to this [1], new car dealerships have a profit margin of 1-2% while auto manufacturers have a profit margin of ~10%. Anecdotally, some dealerships have no profit on vehicles, and rely on services contracts to drive profit.
I interpret this to mean that there is significantly more competition between dealerships than auto-manufacturers. If a consumer wants a specific brand, they can choose between dealers and often will travel long distances to get the best price. When a dealer buys a brand, there is a single supplier with global monopoly.
I think the disproportionate share of profit already going to manufacturers also undermines your argument on the trade-off between sales volume and splitting of profit.
In line with the above, private sellers are generally amenable to haggling because it doesn't matter that it doesn't scale. So when buying a used anything on Kijiji, haggling is expected, particularly if it says "OBO" (or best offer), but not if it says "firm".
If the price is set semi-arbitrarily at the time of purchase, like some U-pick auto junkyards, the person setting the price is right there anyway, so haggling may be acceptable.
I haven't researched any of this; this is just my intuition from experience.
Anyway, being able to advertise a price as firm does provide a convenient escape hatch in that scenario.
You'll often see this when selling used stuff in America. Poor people will haggle to the end of time because every dollar matters to them - something that manifests in selling something at a higher price being more risk-free than selling something at a lower price. For the same reason, if anything goes wrong with the used product they will be upset with you. Because every dollar counts to them.
I throw away cheap stuff instead of Craigslisting it because of the danger of it only being worth buying to poor people.
By the way, Americans prefer calling it 'negotiating'. You 'negotiate' a lower price, you don't haggle things down to a lower price.
They're baking in a fixed profit on used inventory and the customer has no option to impact their profitability and reduce acquisition cost. Now that I think about it, I am going to buy long terms puts on their stock,as this event should completely destroy their business.
Consider every dealership horror story you've ever heard. Both from customers -and- floor employees.
In both cases, having all dealerships across the country owned by the MFG means there's larger pools of workers to unionize, and a greater risk for a class action.
A phrase the older Chinese folks use a lot in my building is "the older generation" or "the younger generation". As in, "the younger generation likes buying things online", or "the older generation prefers making a phone call".
It's made me think more generally about generational differences and how they affect buying patterns, and patterns of doing business generally. I realized, for example, that I really can't stand dealing with contractors (e.g. HVAC) in the older generation who refuse to use Google Calendar or email, and insist on doing everything over the phone, and face-to-face.
I think this "human face of the company" is a good example of a generational difference at play. I categorically do not want to interact with anyone at a dealership. I get product information from word-of-mouth/friends, YouTube, and other sources. Provided a company put some money into creating a customer experience that offered the same level of customization you'd get from a dealership experience (color, trim level, etc) I would be the first person to make a $20-30K purchase online. Not least of which because I'd be confident they'd have built a system not to fuck up my order vs. however it would get input by the person at the dealership who inevitably needs to enter it into the OEM's system to order it.
More and more it feels like I'd rather just rip the humans out and deal more directly with a company's back-office systems (e.g. for placing a car order), than have to play a giant game of telephone explaining something, only to have a human screw it up when entering it. It also annoys me when I call customer service and they remind me 20 times that I should use the website. Of course I should use the goddamned website. I wouldn't be calling customer service if I didn't try that first. This is probably something that won't change until people now in their 20s/30s are in positions to make these decisions in companies, at which time there will be some new trend the "oldsters" don't get. So it goes.
