“Figures from” is the group of build years behind each card's MOT figures. Years where one generation gave way to the next can sit in a wider group until there's enough history to split them.
By build-year group
How each group of build years performs
Each card shows MOT results for one group of Lexus GS build years. “Age” means the car's age on the day of its MOT, not its build year. “25+” groups every test on cars aged 25 or older.
