Well as I promised on a previous post, the outcome of my vibration issue. It took four trips to the dealer, two E-Mails and 7 phone calls the Lexus and we have fixed the problem, when I told they where to look. The left rear wheel had 5 times the amount of weight as the rest, a dead give away, the heavy spots on the tire and rim were too close thus requireing huge amounts of weight. By keeping the heavy spot on the rim and tire opposite one another you are able to add small amounts of weight to bring the wheel into balance. After this was done the car is as near perfect as possible. I have 3000 miles on the car and I'm always looking for excuses to drive it.
