I remember seeing the first VW "Bug" and thinking that ugly wreck will never sell. And later the Honda Civic thinking "more Japanese junk." The odds were against them but had important qualities that made them good values.
My advice to a Volt buyer would be get a short term loan if you finance it, because you don't want to be owing any thing on when the batteries short out and have to be replaced..
My best advice to a prospective Volt buyer is, "Don't."
Anyone who buys a Volt (Dolt) also gets a free mental evaluation through nobamacare.
