Okay, a scraper car is a special kind of car. It's made to go really low to the ground so it can drive over bumps and stuff. The bottom of the car has a lot of metal on it that scrapes against the ground when it goes over bumps. This might sound weird, but people like it because it makes a cool sound and looks really cool too!
Scraper cars also have special wheels and tires that help them drive better when they're really low to the ground. They might have bigger back wheels than front wheels or special tires with a lot of grip.
People who drive scraper cars usually like to customize them a lot too. They might paint them cool colors, put stickers on them, or add special lights or decorations. It's kind of like a big toy car for grownups!
