## Verdict

- **Best value year**: 2020
- **Ideal trim**: GT Line
- **Target mileage**: 30,000–50,000 miles
- **Max previous owners**: 2
- **Target price**: £13,145

## Why this model

The Peugeot 508 is a stylish and comfortable executive saloon (or estate, if you go for the SW). It offers a premium feel without the premium price tag of German rivals, boasts good fuel economy, especially with the diesel engines, and has a distinctive design that stands out. It's a solid choice for someone wanting a refined and practical car for longer journeys.

## What you should pay

Based on current UK market data for a 3-4 year old Peugeot 508 GT Line 2.0 BlueHDi with around 30-50k miles, you should aim to pay around £13,145. Prices have softened slightly in the used market, so there's good value to be had. Be prepared to negotiate, especially if a car has slightly higher mileage or minor cosmetic imperfections.

## Which trim to buy

The GT Line trim is definitely the sweet spot for the 508. it gives you all the sporty looks with its unique grille, larger alloys, and twin exhaust-style finishers, plus a fantastic interior with the i-Cockpit, part-leather seats, and a good infotainment system. You get a lot of premium features without jumping to the top-tier GT, which can be significantly more expensive for not much extra benefit.

## What to check before you buy

- AdBlue system faults (check warning lights and service history)
- Infotainment system glitches (ensure touchscreen is responsive)
- Minor electrical gremlins (test all buttons and features)
- DPF issues if primarily used for short city drives

## Running costs

For a 2.0 BlueHDi diesel, expect fuel costs to be around 12-13 pence per mile. Road tax (VED) for a 2020 model will be approximately £165 per year. Insurance will be moderate, typically in the £500-£800 range annually for an average driver. Expect annual running costs (fuel for 10k miles, VED, insurance) to be in the region of £2,000-£2,500, not including servicing and consumables.

## Key stats

- **Fuel Type**: Diesel
- **Horsepower**: 160-180 hp
- **Mpg**: 50-60 MPG
- **Reliability Score**: Good
- **Safety Rating**: 5 Stars (Euro NCAP 2018)

Buying a 2020 Peugeot 508 now means you're letting the first owner take the biggest hit of depreciation. The car has already lost a significant chunk of its value, and from here on, the depreciation curve flattens out, meaning you'll lose less money year-on-year compared to buying new or a much younger used car.

Total value lost since new: 37.55%.
