I am to pick up a new GS300 this week. After placing the order last week, the salesman at the dealer tried to sell me on a Simoniz paint protection finish. I have been a Lexus owner since 1992, and have bought my last 3 from the same salesman as this. I have never had a dealer applied protection on any other Lexus and am quite skeptical about the need on this car. Frankly, I am somewhat taken aback that the Lexus dealer is descending to the level of pushing such a product. Any feedback or advice to give me?
