I bought mine from a dealer in the Bay Area who said they do not discount the "IS F" but according to them I was the first that they would do this for because this will be my fourth Lexus that I've bought from them and I wound up gettin around $800 off the sticker price of $60,995.
I figured you were bustin' people's chops that's all !! I hope you didn't get offeneded.
PS: ANYONE that refers a customer to me that buys a car, I will pay you a Bird-Dog fee !!! Just make sure they mention your Screen name, and once the car is delivered, I will IM you for your information!!
