I know what heritage lines mean or have an idea what they mean, so I want to trace this back a ways (almost to the beginning). I found this photo on flicker of an old GM truck from the early 1900's..... Now I consider that a beautiful truck..... now these "heritage lines" follow through to the 1950's to some degree... Then something went seriously wrong..... not sure who at GM was smoking something other than tobacco... While this truck still has "character" it marked a change, now I like this truck, but it was a major change. Then..... it sets in.... This is the basic design of the "modern" GM (Silverado/Sierra) that we know today GM only "deviated" to some degree from this design the year I bought my truck, the front end is slightly different, the whole "Box/Brick" look is gone and there the corners have been rounded out to give it a "sleek" modern look (see signature pick). That being said, yes trucks are bricks going down the road, but they can be ugly bricks or they can be good looking bricks. Everyone likes a good looking brick that is functional. That brings me to the 2014's. GM did not follow any "heritage" lines in the 2014 unless the GM trucks heritage started in the late 1960's (Which is obviously wrong). Maybe if GM really went back to its roots for the "look" of their trucks, we would have GM trucks that looked like Dodge truck's from the outside, while everything underneath the truck would be Vortec or Duramax. This: and This: Share absolutely nothing when it comes to looks and the 2014 should be disgraceful to GM truck enthusiasts.
