A 1978 Porsche 911 (G-body) comprehensively transformed by Long Island-based specialist gProgramm, this car — nicknamed 'Mercy' — is the second example the builder completed. The conversion included a bare-metal respray in Slate Grey, a twin-plug 3.4-litre 320 hp engine hand-built to blueprinted specification, 986 Boxster brake upgrade, adjustable coilovers, bespoke interior with tartan trim and a 917-style gear knob, and Fikse Fuchs-style wheels. In 2017 it participated in a cross-country promotional drive to Luftgekühlt 4 and was featured on the Smoking Tire 'One Take' series.
