I wouldn't give it much though. unlike a traditional ICE, the volt engine is automatically controlled. It's not really possible to "abuse" the engine; race it, etc. As for all the important electrical bits, serious warranty coverage on a lot of it so again, not much worry and with maintenance being less frequent than most cars, I think they're a bit more forgiving. I would suggest however having anything you want to buy inspected by a Volt tech unless perhaps if you're buying directly from a Chevrolet dealership. I bought my '13 with almost 93K and never really was terribly concerned with the mileage and so far in the past 5 months or so, it's been problem free aside from a failed window regulator.
