## Why this model

The Mercedes A-Class is a fantastic choice if you're looking for a premium hatchback that feels a cut above the rest. It's got a really stylish interior with that impressive MBUX infotainment system, making it feel modern and high-tech. The ride is comfortable, especially on longer journeys, and the diesel engines (like the A200d) offer a great balance of power and excellent fuel economy. It's a solid choice for someone wanting a bit of luxury and badge appeal without going for a much larger car.

## What you should pay

Based on current UK market data (February 2026), a 2021 Mercedes A-Class A200d AMG Line Executive with around 30,000-50,000 miles is typically selling for around £20,000. This is a really competitive price for a premium hatchback of this age and spec, offering significant savings over new. Prices can vary a bit depending on exact mileage, condition, and optional extras, but aim for this ballpark.

## Which trim to buy

The AMG Line Executive trim is definitely the sweet spot for the A-Class. It gives you all the sporty looks with the AMG body styling and larger alloys, which really make the car stand out. Inside, you get the upgraded 10.25-inch MBUX screens, ambient lighting, and sports seats, making it feel much more premium than the entry-level models. It's the most popular trim, so it holds its value well and is easier to sell on when the time comes. You get a lot of car for your money without jumping to the much pricier AMG performance models.

## What to check before you buy

- MBUX infotainment system glitches (software bugs, freezing)
- Rear suspension noise (creaking/rattling on some models)
- 7-speed DCT gearbox can be clunky at low speeds
- DPF issues on diesel models if not driven on longer runs regularly
- Minor electrical gremlins (sensors, warning lights)
- High tyre wear, especially on AMG Line with larger wheels

## Running costs

For a 2021 A200d Diesel, your running costs will look something like this: Fuel will be around £0.11-£0.12 per mile, assuming diesel at £1.50/litre and 55-60 mpg. Road tax (VED) for a car registered in 2021 is £180 per year. Insurance can vary quite a lot, but expect to pay roughly £600-£900 annually for an average driver, depending on your age, location, and no-claims bonus. Servicing costs for a Mercedes can be a bit higher than mainstream brands, so factor that in too.

## Key stats

- **Fuel Type**: Diesel
- **Horsepower**: 150 hp
- **Mpg**: 55-60 mpg
- **Reliability Score**: Good
- **Safety Rating**: 5-star Euro NCAP (2018)

## Trim comparison

| Trim | Price new | Price used | Key features |

| A 200d AMG Line Executive | £32,000 | £20,000 | 18-inch AMG alloy wheels; AMG body styling; Sports seats |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £20,000 | 100% |
| 2027 | £17,500 | 87.5% |
| 2028 | £15,500 | 77.5% |
| 2029 | £13,800 | 69% |
| 2030 | £12,500 | 62.5% |

Buying a 3-4 year old Mercedes A-Class like this 2021 model is a smart move for depreciation. The steepest drop in value happens in the first few years from new. By buying it now, you're letting the first owner take that big hit, and you'll experience a much slower rate of depreciation over your ownership period. It's a great way to get a premium car without losing a fortune.

Total value lost since new: 37.5%.
