The very low budget, usually unfinished, homemade hot rods built out of 20s and 30s chassis. Not the nice, refined street rods with rack and pinion and four wheel discs...we're talking rough and often ugly, but with a charm of their own.
Primered, pinstriped, mexican blanket upholstery, no chrome, no billet, not much by way of creature comforts...you get the idea. Kinda of a subculture these days.
They had a display of Rat Rods in the Cobo Hall basement during the Autorama. I found some of those cars and trucks to be more interesting and appealing than many of the glitz and glitter creations upstairs.
Others were just plain junk hauled in from the back 40.
