My 2002 Boxster speedometer is at least 5 mph fast at most speeds, maybe even a little more at high speeds. I just read in the NY Times that Honda has been sued for this same problem because it not only registers your speed incorrectly, it also overstates your mileage and, in effect, shortens your mileage warranty. The Times article
(find it here: http://www.nytimes.com/2008/03/30/automobiles/30MILEAGE.html) goes on to say that German cars are the worst for speedo error, but doesn't mention Porsche specifically. Surely, there's no technological reason for this great an error; after all, it's just a matter of counting and calculating, something that anybody with basic math skills could do. So the overstatement of speed, and hence mileage, must be intentional. Honda avoided prolonged litigation over the problem by offering its customers a 5% increase in mileage before their warranties expire. Anybody think Porsche would do the same?
