I was reading here they took a 2lt and shoved the diesel into it. the ltz still remained king but i think gm marketed it wrong and will hurt diesel value. they should have had the ltz next to the diesel vs under it. from a consumer and bean counter aspect imagine paying the big premium of diesel and still adding ltz stuff into it... gm to make $ would have to sell it higher then the ltz so less would buy it or would create internal competition... my thoughts
