We're celebrating our 50th episode of Talking Cars! This reader-question-only episode is our way of saying "thanks" to all of our fans, and even some of our naysayers. Can our talkative bunch answer 15 questions in 15 minutes? As you'd expect, topics covered are diverse: We correct our error about automatic 4wd availability in the 2015 Ford F-150, talk Ford Mustang history, discuss the state of Nissan (and our tendency to ignore them), revisit the Subaru WRX, and seriously wonder about buying a Ram 1500 diesel for New York City.
