Porsche announced its national restoration-challenge winners October 16, 2026, following judging at Luftgekühlt 12 in Fayetteville, Georgia. The awards recognize three distinct approaches to classic-car work.

The national winners

Porsche describes extensive rust repair and mechanical rebuilds for Harper’s green Turbo. Gaudin reversed earlier modifications while preserving original finishes and verifying authenticity through a Porsche Classic Technical Certificate.

Orlando’s RS-inspired 993 has a high-revving 4.0-liter engine and won the enthusiast vote. These project descriptions and judging outcomes come from the organizer.

Three kinds of craftsmanship

The distinction between the categories is the useful part of this result. Repairing a badly deteriorated car, conserving surviving original material and deliberately creating a personalized specification are not the same assignment. A successful custom build should not be mistaken for proof of factory originality.

For an owner considering a similar project, the first decision is therefore the goal: preserve what survives, reconstruct an earlier specification or develop a documented personal interpretation. That choice should come before decisions about paint, mechanical changes and replacement parts.

A competition award recognizes a particular project under that event’s judging. It does not establish the market value, condition or originality of another car wearing the same badge. Anyone evaluating a classic should examine the individual vehicle’s records and work performed.

The outcome follows our earlier report on the nine national finalists. That preview describes the regional entries; this report records the subsequently announced winners.
