Could be. I've never even opened the door on one but am interested in the economy. I've had a full spectrum on my list and everything ends up being a compromise. I know that I could keep it but have weighed my reasons and plan to take the buyback anytime from inception to this time next year.
I seriously considered the Volt. Nice car with lots of bells and whistles (though GM dumped HD radio, which I love). However, the lack of space coming from my JSW was a killer. Plus, I've never been in love with GM products (irrational, I know).
Wound up going with the Audi A3 Sportback E-Tron, their plug-in hybrid. Only gets ~15-20 miles on the battery, but has a little more space than the Volt, similar cabin size as the JSW, but shorter, so less cargo room. Gas/highway mileage isn't quite as good as my JSW, but not bad. I drove it hard on the highway home from San Antonio to Houston and got a little over 34mpg. My JSW would've done around 37-38 tops. But my work commute is 5 miles each way so I'll drive most of the week on battery.
As someone else said, there's no point in trying to justify a particular car. Buy what you like. I really like this Audi.
Now, when I sell back my JSW, I'll pay off debt, stick the rest in the bank and have fun.
Oh, and re: the discussion up above about CVT - this one comes with a 6 speed S-Tronic transmission. You can even get paddle shifters if you want, but mine doesn't have them.
