## Why this model

The BMW X5 is a fantastic choice if you're looking for a large, luxurious SUV that's also genuinely enjoyable to drive. It combines premium comfort and a high-quality interior with strong performance and surprisingly agile handling for its size. It's a solid family car with plenty of space and a commanding road presence, making it feel very safe and secure.

## What you should pay

Based on current UK market data for February 2026, a well-maintained 2021 BMW X5 xDrive40d M Sport with around 30,000-50,000 miles should be available for around £37,450. Prices can vary a bit depending on specific options and condition, but this is a good target to aim for. Don't be afraid to negotiate, especially if a car has been on the forecourt for a while.

## Which trim to buy

The M Sport trim is definitely the sweet spot for the X5. It adds a sportier look with aggressive body styling and larger alloy wheels, which really suits the car's character. More importantly, it often comes with a better standard specification, including sport seats, M Sport suspension (which can be adaptive for a better ride), and a more engaging driving experience. It's also the most popular trim, meaning better resale value down the line.

## What to check before you buy

- Air suspension problems (if fitted)
- iDrive system glitches
- Electrical sensor faults
- Heavy brake wear
- DPF issues on diesel models (if mainly used for short trips)

## Running costs

Running a diesel X5 involves a few costs. Fuel will be around 22-25 pence per mile, assuming current diesel prices of £1.50/litre and 35-40 mpg. Road tax (VED) for a 2021 model will be £600 per year (standard rate of £190 plus the £410 premium car supplement for five years from its second year). Insurance can be on the higher side due to it being a premium SUV, typically ranging from £800 to £1500 annually depending on your personal circumstances.

## Key stats

- **Fuel Type**: Diesel
- **Horsepower**: 340 hp
- **Mpg**: 35-40 mpg (combined)
- **Reliability Score**: Good (7/10)
- **Safety Rating**: 5-star Euro NCAP (2018)

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £37,450 | 100% |
| 2027 | £32,956 | 88% |
| 2028 | £29,660 | 80% |
| 2029 | £27,287 | 73% |
| 2030 | £25,380 | 68% |

The X5, like most premium SUVs, experiences its steepest depreciation in the first few years. Buying a 3-5 year old model like the 2021 example means someone else has taken the biggest hit. While it will continue to depreciate, the rate slows down considerably, making it a more stable investment for the next few years. The sweet spot for selling would likely be before it hits the 8-10 year mark or around 100,000 miles, as maintenance costs can start to increase then.

Total value lost since new: 32.23%.
