General Discussion

The car has already been sold the first time; they already made their profit from it. The fact that a buyer is trading in a used car at all doesn't matter to them; it's all about what they do for their next purchase.

There are only 2 possibilities for a manufacturer when people are trading a car in.

1) People trading in your brand of cars to buy a different brand = not good (lost a customer)

2) People trading in your brand of cars to buy another one of the same brand = excellent (retained a customer and made another sale)

Since Edmunds was unable to provide any data on either of those two possibilities, their article or any conclusions thereof are meaningless.
