Chevy thought they had a great idea when they asked you dear car fan and punter, potential consumer, to do their advertising work for them. They forgot you lot are a cynical bunch and the most web-savvy of us are armed with snark and know how to use it. Two user generated 2007 Tahoe ads are very anti-SUV, and these commercials can be seen on the company's own web site. Oops.
On C|Net we can still see these two ads, now that Chevy has wised up and will certainly remove them. So how much did it cost you in bad PR what you saved on agency creative work, Chevy? Might wanna get the beancounters on figuring that out.
