## Verdict

- **Best value year**: 2021

- **Target mileage**: 15,000–25,000 miles
- **Max previous owners**: 2
- **Target price**: £105,000

## Why this model

If you're looking for an SUV that truly stands out and offers a proper Aston Martin driving experience, the DBX is a fantastic choice. It combines the practicality of an SUV with the stunning looks, luxurious interior, and thrilling performance you'd expect from the brand. It's surprisingly capable both on-road and off, making it a versatile luxury vehicle. Buying a used one means you avoid the massive initial depreciation, making it a much more sensible (relatively speaking!) purchase.

## What you should pay

The DBX, like most ultra-luxury cars, suffers significant depreciation in its first few years. This is great news for used buyers! A 2021 model has already taken the biggest hit, meaning you can get into a nearly new Aston Martin for a fraction of its original price. Prices are now stabilising somewhat, but you'll still see a gradual decline. Our target price reflects a well-maintained, mid-mileage example.

## Which trim to buy

The standard DBX V8 is the sweet spot for value. While the DBX707 offers more power, it commands a significant premium and hasn't depreciated as much yet. The V8 is already incredibly fast and luxurious, and finding one with desirable options like the Sport Pack, upgraded audio, or specific interior finishes will give you the best experience without overspending on the '707' badge. Focus on condition and service history over chasing the absolute top-spec.

## What to check before you buy

- Infotainment system glitches (though improved with updates)
- Minor electrical gremlins (e.g., sensor faults)
- Potential for air suspension issues (listen for unusual noises, check ride height)
- Interior trim rattles or squeaks (common in early models)

## Running costs

Running a DBX isn't cheap, as you'd expect. Fuel costs will be high due to its powerful V8 engine and low MPG, expect around 36p per mile at current petrol prices. Road tax (VED) for cars registered after April 2017 with a list price over £40,000 is £580 per year (£190 standard rate + £390 luxury car supplement). Insurance will be very expensive, likely £2,000-£5,000+ annually depending on your personal circumstances. Servicing is also main dealer only and costly.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 542 bhp
- **Mpg**: 19.8 mpg (combined)
- **Reliability Score**: Below average for mainstream cars, but typical for a low-volume luxury brand. Expect higher maintenance.
- **Safety Rating**: Not rated by Euro NCAP

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| DBX V8 | £160,000 | £100,000 | 4.0L Twin-Turbo V8 engine; All-wheel drive; Adaptive air suspension |
| DBX V8 (Well-Optioned) | £175,000 | £110,000 | All DBX V8 features; Sport Exhaust; Dark exterior trim package |
| DBX707 | £195,000 | £150,000 | 697 bhp 4.0L Twin-Turbo V8 engine; Enhanced 9-speed automatic transmission; Carbon ceramic brakes |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £105,000 | 100% |
| 2027 | £95,000 | 90.5% |
| 2028 | £87,000 | 82.9% |
| 2029 | £80,000 | 76.2% |
| 2030 | £75,000 | 71.4% |

The biggest depreciation hit for the DBX happens in its first 2-3 years. Buying a 2021 model means you're stepping in after this initial steep drop, allowing you to enjoy the car without suffering the most significant loss in value. While it will continue to depreciate, the curve flattens out, offering better value retention compared to buying new.

Total value lost since new: 28.6%.
