✓ marks the trim with the conventional better number for that spec — smaller for length, width, weight, fuel use, turning circle and DC 10–80% time; larger for range, cargo, payload, towing, battery and charging speed. Rows like height, wheelbase, ground clearance and seating capacity are shown without a ✓ because the "better" direction depends on your use case (headroom vs garage fit, off-road clearance vs car-park access).
