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.
