## Verdict

- **Best value year**: 2021
- **Ideal trim**: xDrive30d M Sport
- **Target mileage**: 30,000–50,000 miles
- **Max previous owners**: 2
- **Target price**: £28,740

## Why this model

The BMW X4 is a fantastic choice if you're looking for something that stands out from the crowd. It offers that sporty, coupe-like styling combined with the practicality and elevated driving position of an SUV. You get BMW's renowned driving dynamics, a high-quality interior, and a powerful yet relatively efficient diesel engine in the xDrive30d, making it great for both daily commutes and longer trips. It feels premium and offers a comfortable, engaging drive.

## What you should pay

Based on current UK market data for a 3-4 year old BMW X4 xDrive30d M Sport with 30-50k miles, a fair price is around £28,740. You might see prices vary by a few thousand pounds depending on the exact mileage, condition, and optional extras fitted. Always haggle a bit, but this figure gives you a solid benchmark.

## Which trim to buy

The xDrive30d M Sport trim is the sweet spot for the X4. You get a powerful 3.0-litre diesel engine that's smooth and offers plenty of torque, making it effortless to drive. The M Sport trim adds a much more aggressive and stylish look with its body kit, larger alloy wheels, and sportier interior touches. It also often comes with M Sport suspension, which, while a bit firmer, enhances the driving experience without being overly harsh for daily use. It's the most popular trim, meaning better resale value too.

## What to check before you buy

- iDrive system glitches
- Suspension component wear (bushes, linkages)
- DPF (Diesel Particulate Filter) issues if mainly used for short journeys
- Occasional electrical gremlins
- Brake wear (can be accelerated due to vehicle weight)

## Running costs

For the xDrive30d diesel, you're looking at fuel costs of about £0.16 per mile, assuming current diesel prices and around 42 mpg. Road tax (VED) for a 2021 model that likely cost over £40k new will be £580 per year for the first five years, then £190 annually. Insurance can be a bit pricey for a premium SUV, typically ranging from £700-£1200 per year depending on your personal circumstances and no-claims bonus.

## Key stats

- **Fuel Type**: Diesel
- **Horsepower**: 265 hp
- **Mpg**: Around 42 mpg
- **Reliability Score**: Good (average for premium brands)
- **Safety Rating**: 5-star Euro NCAP (based on X3)

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £28,740 | 0% |
| 2027 | £25,866 | 10% |
| 2028 | £23,279 | 20% |
| 2029 | £20,951 | 30% |
| 2030 | £18,856 | 34% |

Buying a 3-4 year old X4 like a 2021 model means you've let the first owner take the biggest hit on depreciation. From this point, the value loss slows down considerably, making it a much more financially sensible purchase. You get a relatively modern car with most of its life ahead of it, without paying the hefty new car premium.

Total value lost since new: 34.39%.
