Alfa Romeo Giulia Years to Avoid
Every car in the 2024 MOT data was tested at the same age as the other cars first registered that year, so each Giulia year is compared with all cars from the same year. Years with 1,000+ tests that were at least three years old are included.
Failed more often than cars their age
No year passed 3 or more points less often than other cars of the same age.
Passed more often than cars their age
- 2017: 90% passed, against 87% for all 2017 cars (3 points higher, 4,796 tests)
A lower pass rate means that year failed its MOT more often in 2024; it does not mean every car from that year is bad. Old cars still on the road are often the best-kept ones, which can lift the pass rates of the oldest years. How a car has been looked after matters more, so check the MOT history of the car you are looking at.
