Does cheaper housing also mean cheaper cars?

I am starting to look at getting a replacement car. I'm considering both new and used. It's interesting that, under my search criteria, a national search shows that other areas of the country have 10% to 30% lower prices for used cars compared to Boston. Most important, I've noticed that areas of the country with lower home prices also have lower used car prices.

Try it yourself.....you will see that Delaware, PA, southern New Jersey, and Michigan have noticibly lower used car prices.
