## Why this model

The BMW 1 Series is a fantastic choice if you're looking for a premium hatchback that's fun to drive, feels well-built, and has a touch of class. It offers a great balance of comfort and sportiness, making it ideal for both daily commutes and longer journeys. The 2021 model, specifically the F40 generation, moved to front-wheel drive (or xDrive all-wheel drive), which improved interior space compared to older models, making it more practical for families or those needing a bit more room.

## What you should pay

Based on current UK market data (February 2026), a 2021 BMW 1 Series 118i Sport with around 30,000-50,000 miles typically sells for around £16,500. Prices can vary by a few thousand pounds depending on exact mileage, condition, and optional extras, but this is a solid benchmark. The market has softened a bit since the pandemic peaks, so you're getting good value for a premium badge.

## Which trim to buy

The Sport trim hits a sweet spot. It comes with a good level of standard equipment, including sport seats, a slightly firmer suspension (which enhances the driving experience without being too harsh), and more aggressive styling than the entry-level SE. It feels premium without pushing the price up too much like the M Sport, offering the best blend of features, looks, and value for money.

## What to check before you buy

- Infotainment glitches
- Minor electrical gremlins
- Occasional reports of noisy suspension components

## Running costs

For a 118i petrol model, you can expect around 32-37 mpg in real-world driving. With petrol prices around £1.50/litre, that works out to roughly 19-22 pence per mile. Road tax for a 2021 model is currently £190 per year. Insurance costs will vary based on your age, location, and driving history, but expect it to be moderate for a premium hatchback. Servicing at a BMW main dealer can be expensive, so consider reputable independent BMW specialists for better value.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 136 hp
- **Mpg**: 32-37 mpg
- **Reliability Score**: Good, but maintenance can be pricey
- **Safety Rating**: 5 stars (Euro NCAP 2019)

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| SE | £25,000 | £14,500 | LED headlights; 16-inch alloy wheels; 8.8-inch infotainment system with sat-nav |
| Sport | £27,000 | £16,500 | 17-inch alloy wheels; Sport seats; Sport leather steering wheel |
| M Sport | £30,000 | £19,000 | 18-inch M alloy wheels; M Sport suspension; M Sport aerodynamic styling kit |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £16,478 | 100% |
| 2027 | £14,830 | 90% |
| 2028 | £13,347 | 81% |
| 2029 | £12,012 | 73% |
| 2030 | £10,811 | 66% |

Buying a 2021 model means the car has already taken its biggest depreciation hit. New cars lose a significant chunk of their value in the first 2-3 years. By buying a 3-4 year old model, you're entering the market at a 'sweet spot' where the depreciation curve flattens out, meaning you'll lose less money year-on-year compared to buying new or nearly new. This makes it a much smarter financial move.

Total value lost since new: 34.4%.
