PRICE. The Volt had a fantastic sales figures because they were giving it away at $6600 for 3 years. Factor in tax rebate and your looking at sub $5000 lease. The Clarity electric with 89 miles of range has waiting list that's longer than the base model 3. The Clarity Fuel Cell aka "Fool cell" has a waiting list for 6 months. I'm trying to get another Clarity electric and the FCV and it's been impossible.
