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
- —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.

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