I recently received coupons in the mail from my Lexus dealer, Lexus of Silver Spring, for a $29.95 oil change and for free vehicle pick-up and delivery (within 30-mile radius of dealership). The coupons are good until February 28, 2006, and our `04 GX470 has about 12,300 miles on it right now so maybe I'll have about 13,500 by the time I use the coupons. Has anyone else received "special offers" for dealer service? Am I correct that the next scheduled service for the GX following the 10K is the 15K?
