I caught a Chevy Cruze diesel commercial the other day and the white coat guys were holding a white cloth over the tailpipe. They pulled it back and with very snug looks, they glanced at the cloth and nodded their approval. Never showed the cloth to the camera.
Still good to see more and more advertising talking about the cleanliness of the CR diesels. I'd really like to see VW start spending more money on their diesel advertising. Seems to be all Audi. Makes me wonder if VWAG is planning on pushing the diesels out of the VWOA line and only offer them as Audis where they can make more profit due to the rings on the grill.
