Thanks for the feedback. It's helpful to know that there are meaningful gains in mpg over the normal V6. I test drove the HAH again today -- hard to organize because dealers have to use cars pre-ordered by other customers. The demand has its negative side -- dealers aren't moving much if any below MSRP. When taxes etc. are factored in, this almost doubles the premium one pays over the EX V6. I may have to wait until the initial rush settles down.
