Ranked #289 car in the UK · SUV · 316 units sold last year
The Aston Martin DBX is the brand's first SUV - the car that secured Aston's finances, pairing a Mercedes-AMG-sourced twin-turbo V8 with genuine pace, a luxurious hand-trimmed cabin and surprising agility for its size. The hotter DBX707 is one of the fastest SUVs made. As a used buy it offers exotic-badge presence and real performance in a usable five-seat package, with the usual hand-built exclusivity and high running costs to factor in.

Uses current UK pump and home-charging prices (DESNZ weekly), typical-driver insurance and manufacturer service intervals. "Fuel per mile" is just the energy input — so an EV at ~9p and a diesel at ~22p make running-cost comparison direct. A guide; your own costs will vary.

How we estimate this
Indicative annual comprehensive premium estimates. The 'Typical' figure represents an average UK driver in each age band; Lower and Higher risk show the realistic spread driven by factors UK insurers legitimately price on (postcode, occupation, claims history, NCB, voluntary excess, modifications). Based on 10,000 miles/yr, £250 voluntary excess, and the no-claims bonus selected above. Always get individual quotes before buying.
Adjust the annual mileage to match how you'll actually use the car. Insurance is what you selected above (age 33-39, typical risk, 3 yrs NCB).

How this model fares at its MOT as it ages — from 3,279 real DVSA test records.
MOT pass rate by age
A 3-year-old DBX passes its MOT 94% of the time; by 6 years that has risen to 97.8%. The y-axis is zoomed to this model’s range so the trend is readable.
Longevity
Not enough older examples yet to gauge longevity.
Survival by registration year
Each point is one registration cohort. Older cars on the left, newer on the right. A flatter line means the model holds up over time; a steep drop means cohorts disappear from UK roads faster.

Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Aston Martin DBX, or your exact vehicle, has any outstanding recalls on the official DVSA service.
Check on GOV.UKOpens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.
A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.
Whole-car theft
Higher
Desirable SUVs like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.
Parts theft
Around average
Parts-theft risk is around average — catalytic-converter theft is the main thing to be aware of on any petrol or diesel car.
Worth doing
Whether driving a Aston Martin DBX into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.
| City | Area | Daily charge | Likely outcome |
|---|---|---|---|
| London | All of Greater London (within the M25) | £12.50 | Likely exempt Petrol from 2006 meets Euro 4. |
| Birmingham | Inside the A4540 Middleway | £8.00 | Likely exempt Petrol from 2006 meets Euro 4. |
| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Petrol from 2006 meets Euro 4. |
| Glasgow | City centre | — | Likely exempt Petrol from 2006 meets Euro 4. |
| Edinburgh | City centre | — | Likely exempt Petrol from 2006 meets Euro 4. |
| Aberdeen | City centre | — | Likely exempt Petrol from 2006 meets Euro 4. |
| Dundee | City centre | — | Likely exempt Petrol from 2006 meets Euro 4. |

Very few franchised outlets — main-dealer servicing means travelling to one of a handful of locations, so budget for that.
For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.
