Our Verdict
This 2004 Porsche Boxster with the 2.7-l
Although the MOT record is recent and clean, it covers only four years and tells you nothing about the period from 2004 to 2022. Ask the seller for the full service history in writing; a 2004 Boxster with 92k miles should have evidence of the major 30k/60k/90k services, including the intermediate shaft bearing and IMS (intermediate shaft) retrofit if applicable, as this is a known Boxster-specific concern. Negotiate on the basis that specialist Porsche servicing is expensive, typically £500-£1,200 per major service, and budget for two new tyres at around £400-£600 fitted. Inspect the fabric hood carefully for wear, delamination, and correct operation of the mechanism, as repairs can run into four figures on early Boxsters. Check the underside for oil leaks from the intermediate shaft, rear main seal, and gearbox, which are common on high-mileage flat-six engines.
The 2.7-litre flat-six in this generation Boxster typically returns around 25-30 mpg in real-world mixed driving, dropping noticeably in town. Road tax sits in a relatively low band for a 2004 petrol car of this size, but insurance is likely to be in group 30-40 depending on the insurer, which is the single biggest annual cost for an owner. Routine maintenance such as brake fluid, coolant, and a minor service is around £300-£500 at an independent specialist, while major items including a clutch or water pump can exceed £1,000. A realistic annual running cost including fuel, tax, insurance, and maintenance is in the region of £2,400-£3,000, which is reasonable for a sports car of this calibre but materially higher than a mainstream hatchback.
The single January 2023 MOT failure related to exhaust CO content at idle and after fast idle, suggesting the car was running rich or had an exhaust or Lambda sensor issue at the time, so check the current state of the catalytic converters and downstream Lambda sensors. Look for oil leaks from the sump, cam covers, and especially the intermediate shaft area on the rear of the engine, which is a well-documented Boxster weak point and can lead to catastrophic engine failure if neglected. Inspect the condition of the tyres, as uneven wear on a sports car often points to worn suspension bushes or coil springs, and examine the brake discs for corrosion pitting given the relatively low annual mileage. Finally, operate the convertible hood fully through its cycle and check the rear window for delamination, a known Boxster hood issue.
The vehicle has covered 92,121 miles over 22 years, equating to roughly 4,187 miles per year, which is notably above the model average annual mileage of 2,299. Four consecutive MOT passes between January 2023 and January 2026, all without advisories, are a positive sign against the broader 37,831-strong Boxster dataset where only 86.2% of tests pass. A single failure in January 2023 was confined to exhaust CO emissions and was resolved on the immediate retest a week later.
Across the 37,831 Boxsters analysed, the model posts an 86.2% MOT pass rate, which is competitive for a 20-year-old sports car, and the most common failure points are windscreen wipers, anti-roll bar links, and headlamp condition rather than structural or mechanical concerns.
