Watch out for Clipped cars out of Texas

Around here in NC you hear the "Cut two wrecked cars in half and weld them together into a good car." From pretty much any mechanic old enough to be retired. But yeah, I didn't think they still did it. Especially with the oem's lightening and heat treating subframes and whatnot, hoping to save money on steel. Worst part is, I don't know of anything that makes it illegal to do so.
