## Verdict

- **Best value year**: 2020
- **Ideal trim**: E300de AMG Line
- **Target mileage**: 30,000–50,000 miles
- **Max previous owners**: 3
- **Target price**: £28,000

## Why this model

The Mercedes E-Class AMG Line, specifically the E300de plug-in hybrid, is a fantastic choice if you're looking for a blend of luxury, efficiency, and sporty looks without the full-fat AMG running costs. It offers a super comfortable ride, a high-quality interior, and enough power for most situations, especially with the electric boost. Plus, the plug-in hybrid system means you can do shorter commutes on electric power alone, saving on fuel.

## What you should pay

Based on current UK market data for February 2026, a 2020 Mercedes E300de AMG Line with around 30,000-50,000 miles typically sells for around £28,000. This is a great price point as the car has already taken its biggest depreciation hit. Prices can vary by a few thousand pounds depending on specific options, condition, and mileage, but aim for this figure.

## Which trim to buy

The E300de AMG Line is the sweet spot. You get the aggressive AMG styling, larger wheels, and a sportier interior without the much higher purchase price and running costs of a full-blown AMG model like the E53 or E63. The 'de' means it's a diesel plug-in hybrid, offering excellent torque and impressive fuel economy when you utilise the electric range. It's a very practical and luxurious daily driver.

## What to check before you buy

- Air suspension problems (if fitted)
- MBUX infotainment glitches
- Brake wear (due to vehicle weight)
- 12V auxiliary battery issues
- DPF issues if diesel engine isn't run enough on longer journeys

## Running costs

Running costs for the E300de can be quite good if you charge regularly. On a standard home tariff (around 28p/kWh), it might cost about 10-12p per mile for electric driving. If you're on a smart tariff like Octopus Go or Intelligent Octopus (around 7.5p/kWh overnight), this drops to about 3-4p per mile. For longer journeys, expect petrol consumption of around 40-50 MPG. Road tax is free until April 2025, then it's £195 per year. Insurance will be on the higher side for a premium car with AMG styling, likely £800-£1500+ annually depending on your personal circumstances.

## Key stats

- **Fuel Type**: Plug-in Hybrid
- **Horsepower**: 306 hp (combined)
- **Mpg**: 100+ MPG (official combined)
- **Reliability Score**: 7/10 (Average for premium segment)
- **Safety Rating**: 5-star Euro NCAP (2016)

## Trim comparison

| E300de AMG Line | £50,000 | £28,000 | All E220d AMG Line features; Plug-in Hybrid powertrain (diesel + electric); Larger battery for electric range |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £28,000 | 0% |
| 2027 | £25,000 | 10.7% |
| 2028 | £22,000 | 12% |
| 2029 | £19,500 | 11.4% |
| 2030 | £17,500 | 10.2% |

Buying a 3-4 year old E-Class AMG Line like the 2020 E300de is often considered the sweet spot. The steepest part of its depreciation curve has already passed, meaning you're letting the first owner take the biggest hit. While it will continue to lose value, the rate of loss will be slower than a brand new car, offering better value retention for your ownership period.

Total value lost since new: 37.5%.
