My local dealer has a tradeup event for 2017 Bolters this Sat only - a 7-hour event. The flyer came in the mail today -- it's a GM promotion of some sort. It claims "you will drive off in a new Bolt for less than your current Bolt". I can't make much sense of their #s , but of course if it sounds too good to be true, it probably is. Anyone else get this promotion? Anyone figure out what they're actually offering?
