No Altima hybrids - they are only sold in a few states.
Typically with specialty cars like that, the dealer is required to buy $10,000 + worth of special tools and spend thousands more on training for 1 or 2 techs so that they're certified to work on them. After all of that, THEN he can sell the car. the big benfit of hybrids is significantly improved city mpg, and since there are few large urban areas in iowa, most/all of their nissan dealers probably just decided it wasn't worth the expense to be able to sell them.
Ha, that's funny that they're using that, but it's perfectly legit when they say things like "up to 36 mpg" or whatever. The older window stickers used to say "80% of vehicles will get between 25 and 35 mpg city" in the fine print instead of "the majority". The reasons are many, not just driving habits/maintenance/tire pressure/age of vehicle/etc, but there are also significant differences between 2 brand new cars sitting side by side. You can have sequentially vin-number vehicles get 10 mpg difference in some extreme cases. The EPA guideline is simply an average, and it's a rough average at that. It's best used to compare different vehicles, so that if you compare a 30mpg altima to a 20mpg dodge truck, you can be resonably certain that you'll get around 10mpg more in the altima (keeping in mind that the trucks are really 15-25 and the altima is really 25-35).
