- **Target price**: £25,000

## Why this model

The Mercedes C-Class AMG Line is a fantastic choice if you're looking for a car that blends luxury, comfort, and a sporty feel without going for the full-fat AMG performance models. It looks sharp, feels premium inside, and even the C220d diesel engine offers a good balance of power and impressive fuel economy, making it a solid daily driver. It's a very desirable car on the used market, holding its value reasonably well for a premium saloon.

## What you should pay

Based on current UK market data for a 3-4 year old C220d AMG Line from 2021 with around 30-50k miles, you should be aiming to pay around £25,000. Prices can vary a bit depending on the exact trim (Premium or Premium Plus will be a bit more) and condition, but this is a strong benchmark. Don't be afraid to negotiate, especially if a car has been on the forecourt for a while.

## Which trim to buy

The AMG Line Premium trim hits the sweet spot for value. It gives you all the sporty looks of the AMG Line, but crucially adds some really nice-to-have features like the larger digital instrument display, a bigger media screen, ambient lighting, and a reversing camera. These features significantly enhance the driving experience and cabin feel, making it feel much more modern and luxurious than the standard AMG Line, without the higher price tag of the Premium Plus.

## What to check before you buy

- Infotainment glitches (especially early MBUX versions)
- AdBlue system sensor failures (on some diesel models)
- Rear coil spring fractures (less common on newer models)
- Wear on brake discs and pads due to performance-oriented driving

## Running costs

Running a C220d AMG Line is pretty reasonable for a premium car. Fuel costs for the diesel engine will be around £0.13 per mile, assuming current diesel prices and 55 mpg. Road tax (VED) for a 2021 model is typically around £180 per year. Insurance can be a bit higher due to the 'AMG Line' branding and desirability, so expect to pay anywhere from £700-£1200+ annually depending on your personal circumstances.

## Key stats

- **Fuel Type**: Diesel
- **Horsepower**: 194 hp
- **Mpg**: 55-60 mpg
- **Reliability Score**: Good
- **Safety Rating**: 5-star Euro NCAP

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £25,000 | 100% |
| 2027 | £22,000 | 88% |
| 2028 | £19,800 | 80% |
| 2029 | £18,018 | 72% |

Buying a Mercedes C-Class at 3-4 years old (like a 2021 model today) is often the sweet spot for depreciation. The steepest drop in value happens in the first few years, so you're letting the first owner take the biggest hit. From this point, the depreciation curve flattens out, meaning your car will lose value at a slower rate over the next few years compared to buying new or nearly new.

Total value lost since new: 34%.
