Wingho Auto Classique, Inc. was a Montreal-based specialty coachbuilder known for producing one-off and extremely low-volume reinterpretations of Porsche platforms. Its best-known projects were the Porsche 928 Spyder and the W3 Triposto. The 928 Spyder was described as a single surviving prototype derived from a 1978 Porsche 928 that retained the 4.5-liter V8 and five-speed manual but replaced much of the factory body with a custom fiberglass speedster-style shell; later reporting linked the prototype to a 1993 conversion-kit design that did not proceed beyond the one-off build. The W3 Triposto was presented as an open three-seat Porsche 911-based custom with a center driving position, built by Clyde and Hugh Kwok of Wingho Auto Classique, and described as constructed from fiberglass, carbon fiber, and Kevlar; period coverage placed its build in the mid-2000s and characterized it as a hand-built conversion offered at supercar-level pricing. These projects were treated in contemporary coverage as bespoke engineering and styling exercises rather than series-production automobiles, and they were marketed primarily as unique conversions on donor Porsche chassis.
