Lexus average
72.3%
UK average, all cars
The GS runs 3.3 points behind the Lexus average. It is 7th of the 10 Lexus models in the data. The average GS arrived at its test 15.5 years old with 102,082 miles recorded.
A pass rate records whether cars met the roadworthiness standard on test day. It is not a reliability score, and part of any gap reflects how old the tested cars were.
GS MOT pass rate by age
The same 2025 tests split by the car's age at test.
Lexus GS cars aged 6 to 10 years passed 91.2% of MOT tests. For cars aged 11 years and over that fell to 77%, a drop of 14.2 percentage points.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 3 to 5 years (small sample) | 3 | 100% | 27.7 pts above |
| 6 to 10 years | 1,899 | 91.2% | 18.9 pts above |
| 11 years and over | 5,425 | 77% | 4.7 pts above |
That is a steep decline with age, so the headline rate flatters older examples. The UK average of 72.3% covers cars of every age, so compare like with like.
