I think the odor problem should be addressed, but it is irrelevant when it comes to VW. The point in making the comparison to other cities is to say that Chattanooga is certainly not a less desirable place to put a company like VW than many other cities, which the author of the article seems to be implying. In my opinion it is a much more desirable city and obviously VW felt the same.
Call me a conspiracy theorist, but I suspect there is some liberal agenda behind this article. I'm sure it doesn't make them too happy that VW brought their company to a right-to-work state since they are in bed with the unions. They would love to tarnish the city's name. But this article is SUCH A JOKE! I have lived in both New York and New Jersey and I have never smelled anything in Chattanooga that can compare to what I have smelled up there, and on a much bigger scale. But the article is intended to target people who are unaware of this fact.
