So I had to run to Florida to visit family this week and they have a Porsche dealership in Melbourne Beach. Stopped in to test drive a 2003 Boxster S (just playing, not interested in buying) and noticed that they had a base 2008 that listed 27 mpg for the highway (not the 32 mpg Porsche had originally given for the 2.7L engine) on the window sticker. I guess that reflects the new EPA method for estimating the mileage.
