## Verdict

- **Best value year**: 2021
- **Ideal trim**: Performance Line

- **Max previous owners**: 2
- **Target price**: £22,000

## Why this model

The DS 7 Crossback is a stylish and comfortable SUV that offers a touch of French luxury without the hefty price tag of its German rivals. It's a solid choice for someone looking for something a bit different, with a focus on interior comfort, unique design, and a smooth ride. Used models offer excellent value, as they've taken the biggest depreciation hit.

## What you should pay

Based on current UK market trends (February 2026), a 2021 DS 7 Crossback 1.5 BlueHDi Performance Line with 30-50k miles typically sells for around £22,000. Prices can vary by a few thousand pounds depending on exact mileage, condition, and specific options, but this is a strong target.

## Which trim to buy

The Performance Line trim hits a sweet spot. It looks fantastic with its sporty styling cues, Alcantara interior accents, and larger alloy wheels, giving it a more premium feel than the entry-level Elegance. Crucially, it also comes with a good array of tech and comfort features without pushing the price up to the more expensive Prestige trim, making it the best value for money on the used market.

## What to check before you buy

- Infotainment system glitches
- AdBlue system faults (common for modern diesels)
- Minor electrical gremlins
- Some reports of suspension noise

## Running costs

For a 1.5 BlueHDi diesel, you're looking at decent fuel economy, around 55-58 mpg. At current diesel prices (approx. £1.55/litre), that's about 13p per mile. Road tax (VED) for a 2021 model is £180 per year. Insurance costs will vary but expect to pay £500-£800 annually depending on your personal circumstances. Servicing costs are generally in line with other premium European SUVs.

Buying a 2021 model means you're getting a car that's already taken the steepest hit in depreciation. The initial years are when cars lose the most value, so by picking a 5-year-old model, you're letting the first owner absorb that cost. From here, the depreciation curve flattens out, meaning your car will hold its value more steadily over the next few years.

Total value lost since new: 33.7%.
