Most people buy mainstream brands, and quality is more important with mainstream brands than brands that sell to people who can afford repairs, and with the way gas prices are going I'd imagine a lot of people will opt for the Camry over the ES and eke out a few more mpg. Or even a Camy Hybrid etc for a lower price.
