Just bought 2007 siverado eassist. I know not many out there. Hope all works well. Dealer here in Hawaii, did not know the specifics of eassist. I researched and knew more information that salesman. I could not resist the purchase because of the price $37962. Electric engine does ad an additional punch, but I hope the active fuel management issues were fixed in this new model....I will keep this post updated as needed.
