What's with the "hot rod" a 4 door trend these days?

Look, I understand that beauty is in the eye of the beholder...and I understand that the 707-horsepower Dodge Charger SRT Hellcat can effortlessly blow both doors off any classic muscle or sports car in air-conditioned comfort.

But no one that I knew built a 4 door "hot rod" unless it was a "sleeper".
