I leased my 2013 Volt and in a few months the lease will be up. The residual value built into the agreement is in the $26K range. Out of curiosity I went on KBB to see if maybe it was worth more than that on the private-sell market (greedy me thinking I'd sell it, then give GM their resid value and pocket the difference). Lo and behold, the "private sale" price on KBB was $17.1K -- and trade-in value a mere $15.5K. That is one heck of a lot of value lost for a car in truly perfect condition with only 17,000 miles on it. Has GM hosed themselves by calculating my lease on the basis of a $26K residual value, or is KBB full of horsefeathers...or is there something I fail to understand that is going on here?
