The fed gives you $7500 as long as you buy or have 3 year lease, 2 year lease is a no go for the $7500. I am not aware of a battery size limitation from the fed. The Feds $7500 goes directly to the manufacture and effectively lowers the lease or purchase cost. The $2500 from the state of CA goes into your pocket. My son is constantly turning on the heated seats, minimal difference in range, one or two miles less. The other accessories make no noticable difference. You can also program the Leaf to heat or cool the cabin prior to your morning commute while it is still plugged in and save the battery in that way. Takes less energy to maintain temps than to heat or cool the cabin 20 degrees.

More and more places to charge every day, Nissan lets any Leaf charge at a dealership for free. Never been an issue for me, but it is nice to know i can pull into a Nissan dealership get a quick charge and a cup of coffee if I need to.

My range numbers are conservative. 80 miles is not problem, no worries. My wife demands the AC when she is in the car, running with the ac I can get 70 miles easily driving 75 to 85mph. If you are worried about your range for a trip slow down to 65 and you get several more miles.

The electric car is a great second/primary car. It is necessary to have the ICE pickup truck or sedan for long trips or hauling stuff, but 99% of the time the electric Leaf gets chosen.
