Yes, junk car buyers will buy a car with severe rust. Rust reduces the value because it damages the body and structural components, but the car could still contain some usable parts, along with the fact that it's still metal.
Different types of rust that can happen to a vehicle include surface rust, body panel rust, frame rust, rust-through holes, and mechanical components rust.
Parts that are usually unaffected by rust include the engine and transmission, catalytic converter, interior components, electrical parts, glass and mirrors, and aluminum wheels.
When getting quotes, be specific about the rust on your vehicle and where it's located. Junk car buyers expect rust no matter the severity of it. You won't get as much for a rusty car, but it's still worth its weight in value at the least.
