I'm torn on the high priced squares. On one hand the ones that are like the step side are beautiful and should command more. The cheap side of me is upset that they are heading the way of the 57 Chevy's when I was in high school. Beater heaps or basket cases are out of reach for a working stiff. I wish I had kept a few of my squares back when you could grab a stock one for $500 (early 1990's)
I've had some really nice and clean originals that met with the chop saw. Particularly an 87 K5 bone stock I bought from an eye doctor. It was immaculate. DMW woes ended that one.
