Frame twist or sag changes the geometry between the vehicle’s frame and the body. When the chassis is distorted, the mounting points that the body relies on shift, so the body panels no longer line up as they should. This leads to misaligned gaps, uneven seams, and panels that don’t sit flush—rubbing or not sealing properly at the edges. That’s why the most noticeable and direct consequence is a poor fit of body panels. The other options aren’t as closely tied to frame distortion: engine efficiency and fuel economy aren’t directly caused by frame geometry, and while a twisted frame can affect ride characteristics, it wouldn’t typically be described as an improvement in ride comfort.
