ADM's will exist until supply goes up. And that is only because there are always fools that will pay it.
Making a list of good and bad dealers to deal with isn't a new idea. Other forums have a big list going already.
The list of non ADM dealers across the country is a short one. The problem isn't finding a non ADM dealer, it's the fact you will be waiting short of forever for your order to come in.
Also, sure a dealer may help you out with something non transactional. But don't think that is because of your "relationship". It's because they are prepping you for the next transaction. Know that.
My neighbor thinks that way. he purchased 130k easy in cars from a dealer near us in the last year. so when he needs a loaner, he gets one no big deal. he likens that to his good relationship with the car manager. I'm like, no bro, he ain't your friend. he knows you have great credit and you dropped 130k+ there already, so yeah you'll get that loaner. He's just waiting on your next purchase.
