How we measure
Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display, 65 such records for Buick alone, model years 1971 to 2025.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and for Buick that means 65 generation rows instead of 65 year-by-year ones. Where a generation offered several body styles, the figures are the base measurements for that generation, which is how the 25 Buick entries below are built.
