In my opinion, Nissan Leaf
In my opinion, Nissan Leaf car doesn't need a thing. Nissan needs to start focusing on their existing Leafs coming up for battery change-outs 8 years down the road as it is now. And don't let the price of same surprise you.. just remember the gas savings over the 8 year$ and fossil fuels you left behind in the ground. That accounts for a few tonnes of GHG's saved. Mother Earth, I am sure, will dub you 'Hero'. I do too.
