From what I have read/researched on the internet the 240V charger is about $1,400-$1,500 MSRP NOT installed. They also indicate $400-$500 to install. If you have the capacity, you should only need to install a 220-240 breaker in you household box and then wire (in conduit) the charger to that breaker. Depends on your electrical knowledge and mechanical skills, but I would install myself. My breaker box is in the garage and all I have to do is have wife switch places with my car so the Volt is right next to the charger. I do not know how long the coiled cord is but with my situation it doesn't matter.
