I just purchased a used 2012 Chevy Volt and I love it. I have already did some upgrades to make it more mine. I am the general manager for a car audio shop in Columbus, Ohio and I wanted something different than all the Honda Accords and Chrysler 300's running around town. I have already upgraded my stereo system (easier than I first expected), and a friend of mine was selling a set of used wheels and tires that I purchased. They are 22 inch chrome wheels with 235-30-22 Nitto Neo Gen2 tires. I know that they will affect my gas mileage and they are not ideal for this car but they do not rub the and fit perfectly on the vehicle believe it or not. Plus with the occupation I am in it is a really good advertising platform. The sound system upgrade sounds spectacular with the little I have done so far. all I have done is added a alpine PDR 4 channel amp to run the mids on the front channel, the rear channel is bridged running the subwoofer. I will upload pics when I have a second. I am really happy with this purchase and love this vehicle. I wanted one when they first came out and the used 13k example I purchased was worth every penny!
