1987 Porsche 928 S4 – Lagoon Green, 16k Miles, Fully Restored and Documented by local 928 specialist.

Ready for years of worry-free ownership, with all scheduled maintenance and preventative work completed.

Introduced in 1987, the Porsche 928 S4 featured a redesigned aerodynamic body and a new 5.0-liter DOHC V8, marking a significant evolution of Porsche’s grand touring flagship. This launch-year example is a standout, presented in the rare and striking combination of Lagoon Green Metallic over Grey Green full leather. Fully stock and meticulously restored, it has fewer than 27,000 kilometres (approx. 16,000 miles) and is offered for sale out of Canada with extensive documentation. Additional gallery of 1400 plus photos available documenting the 170 hr restoration. No expense spared.

The vehicle in detail

Exterior & Paintwork

This 928 S4 is finished in its original Lagoon Green Metallic, complemented by pop-up headlights, fog lights, headlamp washers, body-coloured side moldings, an electric sunroof, and 16” forged aluminum flat-disc wheels.

A full-body paint protection film (PPF) applied in 2021 was professionally removed by the seller in 2023, with the process fully documented in photos. Prior to 2017, the rear bumper cover and drip rails were poorly refinished. In 2023, a top GTA-based specialist performed multiple spray-outs to achieve a 99% match, including correct metallic flake replication. The rear bumper cover, drip rails, and driver’s side rear rub strip were refinished again in 2023 due to cosmetic issues from decal residue and PPF removal. A full paint correction followed, eliminating all swirls and residual adhesive. Additional photos available showing detailed paint meter readings.

Interior Highlights

The interior is upholstered in rare Grey Green leather, featuring:
• Front seat lumbar support with memory functions
• Power-operated sunroof
• Raised steering wheel hub
• HiFi Sound Package
• Factory alarm system

Only one interior flaw was noted—a missing driver’s side floor carpet, which has been replaced with an exact-match piece sourced from Lakewell (requiring the purchase of a full carpet set; the unused pieces are included in the sale). The leather upholstery is in excellent condition, showing only light wear on the driver’s bolster.

Mechanical Details & Recent Service

Powered by a 5.0L 32-valve DOHC V8 rated at 320 hp and 317 lb-ft of torque, the car retains its original engine and 4-speed automatic transaxle with factory-optioned limited-slip differential. To bring the car up to the seller’s high standards, a comprehensive list of mechanical restorations and preventative maintenance has been completed:
