Yep, I'm not disagreeing with your original point, just pointing out that these comparisons have a few variables to consider. At least someone already went to the trouble of creating an index for it.
It's true that modern homes may differ from those of the 1980s or 2001, but homes built from those periods are still for sale, and in my experience are commanding prices in line with homes built more recently. I recently toured a home built around the 70s or 80s with few or no updates as best as I could tell. They wanted $550,000. The house was pending last I checked.
