They were all built in Flint which means they're all Crew Cabs as well as two being LLY's.....

I am in the market for a new Durmax but am having a hard time finding ine with the options/features I want. I was ready to place an order but the dealer started balking about the price so I told them take it or leave it and they choose not to accept my business. GMC or Chevy it doesn't matter. I may have found a GMC CC LB SLE 4x4 D/A LLY a ways from here but as of last night they had not unloaded it. Problem is I can't do anything until I sell my current truck and I will not trade it in.
