The best of NADA 2015 in pictures, sound and action

In case you didn't attend or want to relive the experience, Dealertrack presents NADA 2015 -- in video. On display are three days of automotive insights seen through the lens of attendees at our booth and interviews with some of our top executives. There's also a peek at our annual Client Appreciation Party -- this year at AT&T Park. Please enjoy, and share your own experiences as we look back on the show and look forward to a year of transforming automotive retail.
