Regarding that CRV, Oddessy, Pilot commercial, the Element wasn't included because that commercial was about how those three vehicles have won JD Powers best-in-class for the last two years in a row.
In a marketing publication I was reading recently, it was suggested that heavy adverstising, while effective on very young buyers, can have quite the opposite effect on young adults.
They used the Civic as an example. The Civic became a favorite of young mod-ers and ricers almost completely without the help of Honda's marketing department (but much to the surprise and delight of Honda). The experts in the article suggested that maybe had Honda TOLD this group that the Civic was the perfect hip, inexpensive car for modifiying then it might not have been such a big hit. Their thinking: this demographic doesn't like to be told what's cool.
Maybe that's why Honda has lightened up on the Element commercials. Could be a marketing research desicion.
