About the 2021 Aston Martin DBS
The 2021 Aston Martin DBS is a luxury car. Our records list a 5204cc petrol engine, though engines vary between versions. 474 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. It ranks in the top 4% of all 2021 models for MOT pass rate.
With an average of 7,781 miles recorded at its 2024 MOT tests, Aston Martin DBS owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.
2021 Aston Martin DBS Fuel Costs
The 5204cc petrol engine is on the larger side, so fuel won't be this car's strong point. Expect around 30 mpg in mixed driving, which works out to roughly £1,958 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

Total estimated annual running cost is £2,413 (£201/month), broken down as £1,958 fuel, £200 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 99% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
Aston Martin DBS Reliability Trend
Newer Aston Martin DBSs pass their MOT more often than older ones, by 3 percentage points on average, which is mostly down to age and wear.
Buying a Used 2021 Aston Martin DBS
At 5 years old, the Aston Martin DBS offers good value with plenty of life remaining. Most manufacturer warranties will have expired, so a pre-purchase inspection is worth the cost. If you're flexible on year, the 2018 model has the highest pass rate at 100%.
