Extremely valuable discussion here -- I thank all of you for sharing your extensive knowledge.
I'm stymied on the fast charger situation. I love the car, having test driven it a few times, love the power and pickup (though I've yet tried to cram my entire family into it, even for a short haul.) Wanted to lease one this week. But I too received an email from GM confirming the lack of a retrofit for fast charging. I quote: "You are correct, there will not be a retrofit to upgrade current Spark EVs to be DC fast charge capable. We expect to start offering the charging upgrade on Spark EVs at the end of this year. Hope this works for your timing."
I was planning to wait, but comments here about the lack of chargers have actually started me thinking I'm being silly. I plan to charge it at home, I don't plan to take it cross country, and honestly I can't imagine the odds of having a fast charger placed anywhere I need it to be are very good. For that matter, I can't imagine planning trips that will absolutely require my finding recharging of any kind en route, because from what I hear, public charging stations are starting to fill up here in LA. I picture myself arriving at, say, the Century City Shopping Mall and finding their five charge stations filled with five EVs, and I have to stand around hoping someone shows up to move their car so I can get some power. It's bad enough waiting in line at a gas pump where the typical transaction takes five minutes, but if someone wants to charge their car for a couple hours while they shop, I could wait an hour or more just to find a charging station slot.
Perhaps I should get the lease without the fast-charge option, and plan to charge at home for the next three years, then as as been suggested, toss the keys back to the dealer in 2016 and move on to whatever has evolved as the best choice then.
By the way, I've been offered $199/month (plus tax) with $1k down and $2500 back immediately from the State of CA, so I effectively get most of the first year free (plus a carpool sticker). If that $149/month deal is a California dealer, I'm interested to know where to get it.
