My favorite, probably because I love my Miata, is this one: The music is great--sort of reminds me of the Edward Scissorhand soundtrack.
wasn't the best ad, but I like how they highlighted 3 safety features. Rear cross traffic alert is new to me. Rear camera and blind-spot alert have been shipping on other cars for awhile, esp. the former. But, at least it creates awareness of these features that car, which is the point.
