## Verdict

- **Best value year**: 2021

- **Target mileage**: 30,000–50,000 miles
- **Max previous owners**: 2
- **Target price**: £19,137

## Why this model

The Mercedes CLA is a fantastic choice if you're looking for a car that blends style, a premium badge, and decent running costs. It really stands out with its sleek, coupé-like design, which makes it look much more expensive than it often is on the used market. Inside, you get that classic Mercedes luxury feel with high-quality materials and the impressive MBUX infotainment system. The diesel engines, especially the CLA220d, offer a great balance of performance and fuel economy, making it a solid option for both daily commutes and longer trips.

## What you should pay

Based on current UK market trends (February 2026), a 2021 Mercedes CLA220d AMG Line with 30,000-50,000 miles typically sits around the £19,137 mark. Prices have softened a bit since the pandemic peaks, so you're getting good value for a premium brand. Expect to pay a bit less for lower trims like Sport, and a bit more for higher-spec AMG Line Premium models.

## Which trim to buy

The AMG Line trim is definitely the sweet spot for the CLA. It gives you all the sporty looks with the aggressive body kit, larger alloy wheels, and a more dynamic interior without the higher running costs and insurance of the full-fat AMG models. You get a great balance of style, features, and comfort, making it feel much more special than the entry-level Sport trim, but without the significant price jump of the Premium or Premium Plus packages.

## What to check before you buy

- MBUX infotainment system glitches (software updates often resolve)
- Diesel Particulate Filter (DPF) issues if mainly used for short journeys
- Occasional minor electrical gremlins
- Brake wear can be higher on AMG Line models due to performance focus

## Running costs

For a CLA220d, running costs are pretty reasonable for a premium car. Fuel will be around £0.12-£0.13 per mile, assuming diesel at £1.50/litre and 50-55 mpg. Road tax (VED) for a 2021 model is £190 per year. Insurance can be moderate, typically ranging from £600 to £1000+ annually depending on your personal details and no-claims bonus. Servicing at a main dealer can be pricey, but there are plenty of reputable independent Mercedes specialists who offer better value.

## Key stats

- **Fuel Type**: Diesel
- **Horsepower**: 190 hp
- **Mpg**: 50-55 mpg (combined)
- **Reliability Score**: Good
- **Safety Rating**: 5-star Euro NCAP (2019)

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| Sport | £32,000 | £17,500 | 18-inch alloy wheels; LED headlights; MBUX infotainment system with 7-inch digital instrument cluster and 7-inch touchscreen |
| AMG Line | £35,000 | £19,137 | 18-inch AMG alloy wheels; AMG body styling; Lowered comfort suspension |
| AMG Line Premium | £38,000 | £21,000 | Keyless-Go; Advanced Sound System; Ambient lighting (64 colours) |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £19,137 | 100% |
| 2027 | £17,000 | 88.8% |
| 2028 | £15,000 | 78.4% |
| 2029 | £13,500 | 70.5% |
| 2030 | £12,000 | 62.7% |

Buying a 2021 CLA in 2026 means you're past the steepest part of its depreciation curve. The initial big drops in value have already happened, so while it will continue to depreciate, the rate will be much slower. This makes it a smart buy for retaining more of its value over the next few years compared to buying new or a much younger used model.

Total value lost since new: 37.2%.
