## Why this model

The BMW X7 is a fantastic choice if you're after a truly luxurious and spacious 7-seater SUV. It offers a commanding presence on the road, a beautifully crafted interior with high-quality materials, and a surprisingly comfortable ride thanks to its standard air suspension. The xDrive30d diesel engine provides a great balance of power and economy for such a large vehicle, making it a sensible option for longer journeys and family hauling. It's packed with technology and safety features, making it a very capable and refined family cruiser.

## What you should pay

For a 2020 BMW X7, you're looking at a significant saving compared to buying new, as these luxury SUVs depreciate quite a bit in their first few years. Prices for well-maintained 2020 models with around 40k-50k miles typically sit in the £48,000-£55,000 range. The market for large luxury SUVs has remained relatively stable, but you can find good deals if you're patient. Always compare prices across multiple platforms and be prepared to negotiate, especially with independent dealers.

## Which trim to buy

The xDrive30d M Sport trim is generally the sweet spot for the X7. The 30d diesel engine offers plenty of torque for effortless cruising and decent fuel economy, which is crucial for a car this size. The M Sport trim adds a more aggressive and stylish exterior look, larger alloy wheels, and a sportier interior feel without compromising on comfort. It also comes with a generous list of standard features, including adaptive air suspension, professional navigation, and advanced parking assistance, making it a highly desirable and well-equipped package that holds its value better than entry-level trims.

## What to check before you buy

- Air suspension problems (listen for compressor noise, check for uneven stance)
- Electrical glitches (iDrive system, various sensors)
- Brake wear (heavy car, check discs and pads)
- DPF issues on diesel models if mainly used for short journeys
- Tyre wear (large, heavy car, check inner and outer edges)

## Running costs

Running an X7 isn't cheap, but the xDrive30d diesel helps keep fuel costs reasonable for its size. Expect around 20p per mile for diesel at current prices. Road tax (VED) for a 2020 model will be £520 per year for the first 5 years from new (due to its high new price), then it drops to £190 per year. Insurance will be on the higher side, likely £1,000-£2,000+ annually depending on your personal circumstances. Servicing at a BMW main dealer can be £600-£1,000+ per year, so consider independent specialists for better value.

## Key stats

- **Fuel Type**: Diesel
- **Horsepower**: 265 hp (xDrive30d)
- **Mpg**: 35-38 mpg

## Depreciation forecast

| 2026 | £50,000 | 100% |
| 2027 | £42,500 | 85% |
| 2028 | £36,000 | 72% |

Buying a 2020 X7 in 2026 means you're letting the first owner take the brunt of the steepest depreciation. Luxury cars like the X7 lose a significant chunk of their value in the first 3-4 years. By buying a 3-4 year old model, you're getting a car that's still relatively modern and well-equipped, but at a much more palatable price point. While it will continue to depreciate, the rate of loss will be slower than if you bought it new.

Total value lost since new: 66%.
