Got a great deal on a used 2013 back in May. Three months later and I've used my first tank of gas. Very happy with the car so far, assuming I get the clicking noise caused by the CV joint fixed under powertrain warranty. Currently waiting on parts, which the dealer can't even give me a ballpark eta on.
That's one thing that worries me a bit about the car. Does GM have sufficient stock for Volt parts? I checked GM direct, and it looks like it would take many weeks to order it from there.
