You will enjoy it on the 'dark side' wd15
I have had my Volt (Sparkers) for just a little over a year - and it is the best commuter car I have ever owned. Perfect!
Like you, I got a screaming deal on my '13 - it was a 'promotional car' (I believe used at a golf tournament) and had 153 miles on it - I got it for $27k and with the rebates (fed - $7500 and state - $4500) the car ended up costing me $15k.
My commute is 42.7 miles round trip (see below) - and I get to charge at work (in the photo you can see the charger in the background). So, I hardly ever charge at home, just once on the weekends. My fuel costs are nothing... even in the winter it did great - but it does cycle the engine if it gets too cold - so my mileage isn't as good as some hypermilers... they are getting over 500 mpg.
It has been a very solid car the first year - the only thing, the back seats are a bit tight in the leg room category, and it is so quiet, sometimes you have to peep the 'people horn' because people will just stand around too close the car when you want to get going.
I even took it on a couple of trips last year. I went to OK City and the hotel I stayed at was so cool about the car - they found me a place to plug it in and everything.
So, even with a couple of long trips under it's belt... 211mpg - read it and weep boys....
