Proven Durability Champions: Which Aston Martin Models Age Best?

These Aston Martin models have proven exceptional durability with 11+ years of real-world MOT data. They consistently outperform the national average for cars of the same age:

Overall Aston Martin Durability Rating: Excellent

High-confidence data: Only vehicles with 11+ years of MOT history and 100+ tests are included in this ranking.

Model Year Fuel vs Same-Age Average Tested At Pass Rate
VANTAGE - All +34.4% 15-17 years 92.3%
DB9 - All +32.5% 18-20 years 88.7%
V8 - All +32.3% 18-20 years 88.5%
DB9 - All +32.2% 15-17 years 90.0%
V8 - All +31.9% 15-17 years 89.8%
V8 - All +27.0% 11-14 years 91.6%
VANTAGE - All +25.7% 11-14 years 90.4%
DB7 - All +23.9% 21+ years 84.8%
DB9 - All +23.4% 11-14 years 88.0%

How to read this: A score of "+15%" means the model passes MOTs 15 percentage points more often than the average car of the same age. These are proven results from vehicles that have genuinely aged well.

Proven durability champion

The VANTAGE outperforms the average 15-17 years-old car by 34 percentage points, with 518 MOT tests proving its reliability.

Early Performers: Strong Start, Unproven Durability

These newer Aston Martin models (3-6 years old) show strong early results, but haven't yet proven long-term durability:

Important caveat: Durability NOT yet proven - too early to assess long-term reliability. Older versions of the same model may tell a different story at 11+ years.

Model Year Fuel vs Same-Age Average Tested At Pass Rate
VANQUISH - All +19.9% 8-10 years 95.3%
DB9 - All +18.1% 8-10 years 93.6%
VANTAGE - All +17.2% 8-10 years 92.6%
DBS - All +12.0% 3-7 years 96.8%
DB11 - All +10.1% 3-7 years 94.8%
VANTAGE - All +9.3% 3-7 years 94.1%

What this means: These models are performing well in their early years, but we recommend checking the Durability Champions section above to see how older versions of the same model family have fared over time.

Aston Martin Hybrids vs Petrol vs Diesel

Here's how Aston Martin petrol models perform:

Fuel Type Average Pass Rate vs National Tests

About This Data

This analysis uses real MOT test results from the DVSA database, covering 21,751 tests on Aston Martin vehicles between 2000 and 2023.

Year-Adjusted Scoring (v2.1): In year-by-year breakdowns, each vehicle is compared against the national average for vehicles of the same model year. This removes the natural bias where newer cars pass more often, allowing fair comparisons across eras.

Evidence-Tiered Durability: We separate "proven durability" (vehicles tested at 11+ years old) from "early performers" (3-6 years old). Only vehicles with proven long-term data are used for durability claims. Age-band comparisons use weighted national averages.

Minimum thresholds: 100 tests for proven durability rankings, 100 tests for early performer rankings. Pass rates are calculated as first-time passes, excluding retests.

The overall national average MOT pass rate is 71.44% based on 32,300,000 tests across all manufacturers. Year-specific averages range from ~59% (2009 vehicles) to ~88% (2020 vehicles).
