This 1973 Porsche 911 Carrera RS 2.7 (production number 103 3986) is an M472 Comfort specification example finished in Signal Yellow, one of only 86 RS 2.7s delivered in that colour. First registered in Germany in January 1973, it later passed to a Japanese owner before arriving in the United States, where it underwent a comprehensive nut-and-bolt bare-metal restoration by Dave Imes at Apex Auto in Colorado. It has covered just 1,332 kilometres since that restoration.

Maintenance & restoration

  1. Modification

    Original engine case was swapped for an un-numbered correct-type 91/83 replacement case dated 1974, and the original five-speed gearbox was replaced with a correct 915/08 unit. This work occurred early in the car's life.

    Both replacement components are described as correct-type substitutes for the originals.

  2. Restoration
    Apex Auto

    Full bare-metal, every-nut-and-bolt restoration carried out by Dave Imes. The body shell was found to be largely sound; only the rocker panels and front lid were replaced. A new interior was partly sourced from Tony Garcia and partly fabricated and fitted by a Denver-area specialist. New replica sport seats were installed.

    Restoration was commissioned by the owner prior to the consignor and completed after the consignor acquired the car mid-project.

  3. Maintenance

    Instruments were refurbished by North Hollywood Speedometer, and the Fuchs alloy wheels were refinished by Harvey Weidman.

    Work carried out as part of the broader restoration project.

  4. Modification

    The replacement engine was upgraded with later Carrera-specification pressure-fed timing chain tensioners to improve long-term reliability.

  5. Service
    Blue Chip

    Ongoing expert maintenance carried out following completion of the restoration.

    Blue Chip is described as a Denver, Colorado-based specialist garage. The car has accumulated only approximately 1,332 km since the restoration was completed.

Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
