Our Verdict

A compelling example of a classic Porsche 928 S with an exceptionally clean recent MOT record. While the mileage is high, the lack of recorded defects over the last five years suggests a well-maintained vehicle.

Given the high mileage of 152,950, your primary focus should be on the comprehensive service history. Ensure there is documented evidence of timing belt and water pump changes, as these are critical maintenance items for the 4.9L engine. Request records of any major chassis or suspension overhauls, as the lack of MOT defects suggests the car is currently in good order, but wear-and-tear parts will naturally require replacement at this stage of its life.

Negotiate based on the mileage relative to other 928 S models, but acknowledge the premium associated with a car that has passed five consecutive MOTs with zero defects. Check for any evidence of previous restoration or significant bodywork to ensure the blue paintwork is original or high-quality, as this impacts the long-term collectible value.
