Hi, Ed.
I did a quick search on "pulse and glide" and came up with this thread; maybe it's the one you're looking for. It doesn't have pictures, but it does have graphs:

As far as warranties go, if you buy a used hybrid you can probably purchase an extended warranty if you wish. I got one that extended my car's warranty out to 7 years, which would be 2011. My husband was worried about all the electronics and stuff he's unfamiliar with, so we got an extended warranty for some piece of mind. So I suppose you'd have to enter that cost into the equation, if adding that on top of the price of a used car takes it up too close to what it would cost to buy a new one.
