Right on cue... (Did I call it?) ;-P
We already /DO/ do this at the grocery store or home improvement store - but they are set up as a 'fixed price' system that is very difficult or impossible to override the prices at the register. So when we see the prices at Home Depot or Kroger/Ralphs are too high for our tastes, we just walk out and take our business over to Lowe's or Vons/Pavillions and buy our stuff at the proper price.
The vendors we walked out of either figure it out and get their prices in line with the marketplace, or they go broke.
There might be a dozen grocery stores in your town ranging from supermarkets to convenience stores, or three to four hardware or home improvement stores in the same range of sizes, all selling the same basic items. But there's only one car dealer for any one make. The only exception being major metropolitan areas.
Some dealers will sell a car at a low profit point IF the customer pushes them hard - but if they walk in as a "Barefoot Pilgrim" waving $5,000 over MSRP sticker for immediate delivery on the 'hot car of the month', you certainly aren't going to turn it down, are you?
Of course not! The guy who wants to get a decent deal is just going to have to wait till all the stupid people waving around wads of cash have gotten their new cars, and the demand cools down a bit.
You complain at only making $3,000 gross on a $35,000 wholesale car sale - that's a bit under 10%, which is a LOT of markup for a big-ticket item. What the heck are you complaining about? Real estate agents are fighting over customers to get business at a 3% commission rate. General contractors on remodel jobs can only mark their sub-contractors prices up 10% at the most, many are less when the job is big or times are tight.
And if a car dealership prices themselves out of the repair and maintenance market, smart people will go somewhere else unless they have a warranty issue. I always shop around between dealers and independents for that work, and some dealers are in line with the rest of the market, some are not.
There are always some people who think "Damn the Cost, Factory Service Only!" and that's how some dealers manage to get business even if they have radically overpriced service bays.
It's a free market. You are free to try and "maximize profit on every sale" and we are free to maximize value received. But don't cry crocodile tears when us customers figure it out.
