One minor suggestion for the configurator would be an indicator of whether gas mileage should increase or decrease with certain options (e.g. the chin or deck spoilers). Just qualitative, not necessarily hard numbers or estimates. We all know Yellow is virtually guaranteed to increase mpg by 2% or more, so EM might as well incorporate that into The Configurator (am I the only one who hears an ominous booming echo every time I say "The Configurator?").
Perhaps these sort of qualitiative tests may be part of the E-series testing? Once they've established a baseline, it makes sense to see how some of the options may effect the milage.
