## Why this model

The Porsche Boxster is a fantastic choice if you're after a pure driving experience with open-top thrills. It's renowned for its sublime handling, precise steering, and engaging flat-four engine sound (especially the 2.5L S model). Porsche's build quality is excellent, and while it's a premium brand, the Boxster holds its value relatively well for a sports car. It offers a great balance of performance, everyday usability, and brand prestige, making it a solid choice for a weekend toy or even a daily driver if you don't need back seats.

## What you should pay

Based on current UK market data (February 2026), a 2020 Porsche Boxster S 2.5L with around 30,000-45,000 miles typically sells for around £49,493. Prices can vary by a few thousand pounds depending on specific options, condition, and mileage. While it's a significant investment, the Boxster's strong residuals mean you won't lose as much as with some other premium cars.

## Which trim to buy

The Boxster S 2.5L is the sweet spot in the 718 range. The base 2.0L is good, but the 'S' adds a significant boost in power and torque from its larger 2.5-litre turbocharged flat-four engine, making it much more exciting to drive without being overly aggressive for daily use. It also often comes with desirable upgrades like larger brakes and sportier suspension. The GTS is fantastic but commands a much higher premium, and for most drivers, the 'S' offers more than enough performance and a better value proposition.

## What to check before you buy

- PDK gearbox issues (rare but costly if they occur)
- Water pump failure
- Ignition coil failure
- Minor electrical gremlins (e.g., infotainment glitches)
- Rapid tyre wear (especially on performance models, expensive to replace)

## Running costs

Running a Boxster isn't cheap, but it's manageable for a performance car. Fuel costs for the 2.5L S model will be around 24p per mile (based on £1.50/litre petrol and 34 mpg). Road tax (VED) for a 2020 model will be the standard rate of £190 per year, as the luxury car supplement would have expired by 2026. Insurance will be on the higher side, likely £800-£1500+ annually depending on your age, location, and driving history. Servicing at a Porsche main dealer is expensive, so many owners opt for reputable independent Porsche specialists to save money, but expect bills to be higher than for a regular family car.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 345 hp (Boxster S 2.5L)
- **Mpg**: 30-35 mpg combined
- **Reliability Score**: Generally good, but repairs can be expensive.
- **Safety Rating**: Not officially Euro NCAP tested, but built to high safety standards with excellent handling.

## Trim comparison

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

| Boxster S | £56,000 | £49,493 | 2.5L Turbocharged Flat-Four Engine; 345 hp; 19-inch Boxster S Alloy Wheels |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £49,493 | 0% |
| 2027 | £45,533 | 8% |
| 2028 | £41,890 | 15.3% |
| 2029 | £38,539 | 22.2% |
| 2030 | £35,456 | 28.4% |

Buying a 3-6 year old Porsche Boxster like a 2020 model is often the sweet spot for depreciation. The steepest drop in value happens in the first few years from new. By buying a car that's already a few years old, you let the first owner take the biggest hit. From this point, the depreciation curve flattens out, meaning your annual value loss will be less significant, making it a smarter financial move.

Total value lost since new: 28.4%.

## Alternatives to consider

- Audi TT S Roadster
- BMW Z4 M40i
- Jaguar F-Type Convertible
