Will the Britax Marathon ClickTight fit in a 2024–2024 Chevrolet Trax?

Yes — the Britax Marathon ClickTight fits a 2024–2024 Chevrolet Trax, with a caveat.
The Marathon ClickTight is about 18.5" wide; the Trax's usable rear bench is about 48". It fits one rear position comfortably. Three across is tight (55.5" needed vs 48"). Note: rear legroom here is limited, so a rear-facing install may crowd the front passenger.
