I have spoken with two CALIF dealerships that would argue with your claims, but who cares, hype in sales is the norm, not the exception, in the auto sales world particularly.
Dealers in CA typically could care less if customers believe them or not, their attitude is "buy it at our inflated ADM or get lost." No wonder the far majority of people I know hate buying cars from any dealership. I suppose it falls into that necessary evil until you search the country and find an upright honest dealership that will deal with people squarely.
That's what I found after querying about 30 dealerships all over the USA (including Las Vegas) and settled on (believed) Thoroughbred Ford clear over in Kansas City, MO.
ADM was the norm in unbelievable quantities. I asked one salesman how he sleeps at night - he just laughed.
