I rented a Chevy Spark (a hybrid) a couple years ago and was NOT impressed by it at all. No guts at all -- none, zip, zilch, nada. I had the opportunity to pull into a dealership where a couple of salesman were standing around just to ask them a question about using something on this rental, and they gave me the usual positive upsell -- "but you are getting 32 miles per gallon". I told them I get 50 on my Prius and that shut them up real fast. I have only seen 1 or 2 Chevy Sparks on the road since then. I guess that the Spark, like the Nissan Leaf, just isn't selling. And in Nevada, you just can't find lots of places to plug in your electric vehicle, and recharging takes longer than refilling.
