How is the instrument cluster different for the 09?

New model is unchanged from 08 except new instrument cluster

How did you make the determination that the instrument cluster is different?
If you were looking at the picture it seems to be the same as the 08. the only difference that I could see was the primary speedometer was in kilometers instead of miles per hour.

The pictures definitely reflect and export model. The side lights are required for cars shipped to many foreign countries.
As for any changes to the 09 model, my guess is there will be none. With limited production of these cars, changing the interior or exterior would involve significant expense, inevitably increasing the price. Why change a good thing! Lexus is noted for minimal changes from year to year. I would speculate that more time is being devoted toward developing prototypes such as the ISF coupe and the LFA. Just my opinion!
