OTT but in line with your question
In my part of Australia we have an established dealership who has been here since the 70's and I bought my 1st car from him in the mid 90's.
each couple of years I would go back and ask what he could do for me as a trade and on what.
every time, walking out with a good deal (he actually moved figures around to get the best price)
larger part of my wifes family started going there and same outcome, come home with a car they like, met their expectations and got good trade-ins for their cars.
recently I took mine and my wifes cars in to change over, we picked our cars, got fair to good trade ins on them, paid and then waited on them to be detailed so we could drive home.
I asked the dealer principle which car would he have sold me if he wanted to make money. he said, plainly "they all make money, in differing amounts, no point trying for a high margin car that won't suit either of your needs"
I asked what he could of pointed us at if he wanted more money out of us. his reply "I'd push you to a cheaper 2nd hand car or one of the LDV/MG/Import cars where I would make 3x as much as what I am getting from this sale"
guy is in his 80's and doesn't mince words but is as honest as they come
