I am gonna buy a new Duramax. The thing is i would like it to have the new LLY Motor. An since production date started the 8th. They will be on lots soon I hope. Thing is now GM has a good rebate on the trucks that ends Jan. 4th... If I have to order this truck the way I want it with the new motor will the rebate still apply??? Or is this rebate just apply to present trucks on the lots with the regular LB7 Motor???? Not saying these are bad at all , its just for 40K I want the latest technology. Guess you guys understand..
