While we were researching the new IS we discovered something interesting.
Different regions of the country can get different configurations and pricing on the new Lexus IS.
Here is the configuration screen from the Lexus.com site for a customer in the 92660 (Newport Beach, California) zip code:

Now look at the same car configured in the 14226 zip code (Amherst, New York)
Two totally different choices!
And, it appears that a person in the Eastern region of the USA will pay more for their car...As they say in Canada, interesting, eh?
