The ones that surprise me are Frederick in Ohio, and Wyckoff in New Jersey. Frederick is renowned for being one of the best dearlership experiences in this country, and they are selling Challengers like crazy. Bob Jr is also a columnist at redletterdodge.com. Wyckoff is a big-time parts dealer.
Also of note, but not a surprise to see on the list, is Darner in Mesa, AZ. That's the dealership in the movie "Used Cars" owned by the evil twin brother. BTW, the dealership still totally looks like that. The dealership across the street that was owned by the good brother has been an apartment complex for many years now.
