Which year is which
Build years & generations, side by side
Find the build years you're looking at and see which generation they are. You'll also see which group of build years the MOT figures come from.
Built 2001-2004
- Generation
- Series 1
- Figures from
- cars built before 2005
Counted with every car built before 2005, so much older cars can affect the figures.
Built 2005
- Generation
- Series 1
- Figures from
- cars built 2005-2008
Counted with this generation only.
“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 MG ZR 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.
