Should I check the MOT history before buying a 2021 Aston Martin Dbx V8 Auto?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Aston Martin Dbx V8 Auto?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Aston Martin Dbx V8 Auto?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2021 Aston Martin Dbx V8 Auto reliable?

Based on MOT data from 331 vehicles, the 2021 Aston Martin Dbx V8 Auto has a first-time MOT pass rate of 96.5%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Aston Martin Dbx V8 Auto?

Moderate sample. 331 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2021 Aston Martin DBX V8 clears the MOT hurdle comfortably, with a 93% pass rate that sits well above the UK average of 80%, and only 2.4% of vehicles ever flagged for dangerous defects—a reassuringly low figure. This is a genuinely reliable luxury SUV by MOT standards, with barely any failures averaging out to just 0.1 per vehicle tested.

The median mileage of 21,405 miles is exactly where you'd expect a three-year-old car to sit, suggesting these are properly driven rather than stored, yet the low advisory rate of 0.8 per vehicle indicates the mechanicals are holding up well with normal use. If you're shopping for one, get a pre-purchase inspection to verify the service history—these cars are expensive to fix if maintenance has been skipped—but MOT data confirms the DBX V8 is mechanically sound in the hands of responsible owners.

The 2021 Aston Martin Dbx V8 Auto passes its MOT first time more often than most UK vehicles (96.5% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
