Gesh . The list is at best 50% accurate.
Here is a big thing it is missing. Something even Consumer Reports makes clear. Just like any business, a car dealership (sales, service) only survives as a business if it is profitable. Non of us would have jobs if our company did not make a profit. We do not work for free. Furniture is marked up 300%, so at half off the store doubles their investment. Clothes are similar. Oh let's not forget operating costs by the way.
An informed buyer will usually find a car dealer that runs a fair business. A improperly informed buyer is never going to know what is or isn't fair.
