Well,not to rub anyone the wrong way,but most folks,including here,didn't "get it" till it became the trend it has fairly recently. You can't expect everyone to catch the trend at the same time. You also can't expect everyone to follow the trend. It's the same with everything,not just patina. The patina look is a work in progress/unfinished look,so in a way this guy did get it. One day,most all patina machine will be painted.

The Suburbans were made longer in '67 which allowed a door for access to be added. That's all there is to it. It was a major improvement for use as a family vehicle over years before. The thinking behind it was likely the same as with Vans that only have curbside doors. I guess GM figured adding a 4th door was a further improvement by the time they redesigned the body in '73. The third door would have been a great idea for the Panels that I wish they had done.
