MOT Roadworthiness: Excellent

Our Verdict
A highly attractive example of the 3.4L
Given the very low annual mileage, the primary focus should be on the service history. Ensure that oil and filter changes have been performed at regular intervals regardless of the distance covered, as oil degradation occurs over time. Check for any evidence of the car sitting for long periods, such as flat-spotted tyres or battery health issues.
Verify the date of the last major service. For a vehicle of this age, certain components like coolant hoses or belts may require replacement based on age rather than the recorded 39,116 miles. Use this to negotiate the final price if a major service is imminent.
The 3.4L engine provides significant performance but comes with higher fuel consumption and a higher tax bracket than the smaller Boxster engines. Insurance costs will be reflective of the vehicle's performance and the Porsche brand, likely placing it in a higher insurance group.
Maintenance costs for this model can be high due to the requirement for specialist parts and labour. Between fuel, road tax, insurance, and scheduled maintenance, the annual cost of ownership will be substantial compared to a standard road car.
While this specific vehicle has a clean MOT record, the wider Boxster model is known for failures related to the exhaust system, brake pipes, and headlamps. A physical inspection of the underbody for corrosion or exhaust leaks is recommended to ensure these common model weak points are not present.
Additionally, thoroughly test the operation of the convertible roof mechanism and check the seals for any signs of perishing. Since the MOT does not always highlight minor roof leaks or slow mechanism operation, this is a critical area for a prospective buyer to verify.
This silver 2008 Porsche Boxster has a recorded mileage of 39,116 miles as of March 2026. Its recent MOT history is notable for five consecutive passes without a single defect recorded between 2022 and 2026. It represents a low-mileage example of the larger 3387cc petrol engine variant.
The Boxster maintains a solid aggregate MOT pass rate of 86.4%, with the most frequent failures occurring in the exhaust and braking systems.

Historical MOT pass rates and DVLA records for 2008 model year cars.
- Bore Scoring (987.1)Serious
3.2 and 3.4 engines are at risk, requiring expensive specialist rebuilds.
- Radiator / Condenser CorrosionModerate
Front intakes collect leaves and road salt, rotting the cooling components.
- IMS Bearing (987.1)Serious
The intermediate shaft bearing on early 987.1 models (2005-2008) shares the same risk as the 996/997.1. The 987.2 (2009+) eliminated the IMS bearing entirely.
