As one of the volume models in the Lexus lineup, it’s critical to get the 2007 ES 350 exactly right. If the company tries to infuse the car with too much performance, it will turn off the traditional buyer who values a comfortable and quiet ride. Yet, the ES 350 must be powerful and responsive enough to appeal to buyers who might otherwise select a competing model. Balancing this mix of power and performance, comfort and luxury, is not easy.
