2009 Porsche Cayman 3.4L Petrol · WR09 OTG

The 2009 Porsche Cayman presents a mixed maintenance picture. The most recent MOT, conducted on 3 January 2026 at 71,333 miles, passed but flagged three advisories, indicating a slight decline in the vehicle's mechanical condition compared to the clean bill of health recorded just weeks earlier in December 2024. The tester identified severely deteriorated constant velocity boots on both the nearside and offside rear outer drive shaft joints, alongside slight play in the offside front lower suspension arm ball joint. While these did not constitute failures, the CV boot deterioration suggests potential exposure of the joint to debris and moisture, risking costly drive shaft replacement if left unaddressed. The trend is not sharply worsening, but the accumulation of minor suspension and drivetrain advisories points to a vehicle that may be entering a phase of deferred maintenance. The mileage profile is notably low for a seventeen-year-old sports car, averaging roughly 4,196 miles per year. The record shows a significant gap between August 2023 at 56,436 miles and December 2024 at 68,308 miles, representing over 11,800 miles covered in approximately sixteen months. This suggests a shift from prolonged light use to more regular driving. Prior to that gap, the vehicle covered just 13,382 miles between August 2022 and August 2023, reinforcing the pattern of inconsistent usage. The sparse MOT history, with only five recorded tests across four years, limits the ability to draw firm conclusions about long-term care, though the clean pass in December 2024 at 68,308 miles indicates the car was in solid mechanical order at that point. A prospective buyer should focus their physical inspection on the front suspension and drivetrain. The recurring advisories around the nearside front lower suspension arm ball joint, flagged in both August 2023 and January 2026, suggest this component may be approaching the end of its service life. The corroded nearside front coil spring noted in August 2024 warrants close examination for structural integrity, as corrosion on spring coils can compromise load-bearing capacity and ride height. Both rear outer CV boots were severely deteriorated at the January 2026 test, so the buyer should verify whether these have been replaced and inspect the joints for play or clicking under load. The slight play flagged in the nearside front wheel bearing in August 2024 should also be rechecked, as wheel bearing wear can progress quickly on a performance vehicle subjected to hard cornering loads.
