Q/001 · Trims and packages

What does trim mean on a car?

"Trim" (also called trim level) is the manufacturer's name for one specific, pre-set equipment bundle within a model line: it is a marketing label, not a technical or regulatory term, so the same word describes different things from one brand to the next.
