Chevrolet has a deal with Bosch electric vehicle solution (this is probably an unit of bosch, see http://www.pluginnow.com/) for $500 off the price of a home charging station. Which is pretty substantial, since a decent charging station is north of $700. Once i leased my spark, i called those guys and they were very helpful. Yet they asked me to fax them the $500 coupon that i got from the dealer. The dealer said they have no such coupons, and Chevrolet customer service didnt know how that deal is executed either. Anyone has any sort of experience on this particular deal?
