Lexus is the top-selling luxury auto brand, thanks to the IS, ES and LS models being popular among buyers willing to spend $30,000 and $75,000 on a vehicle.  Overall, luxury sales have more than doubled since 1999 to 1.9 million units.

Now Lexus wants a piece of the growing upper end of the luxury market, where Mercedes and BMW sell vehicles for more than $100,000.
