Real-Build Mode (museum-quality clone logic baked-in): LEGO-legal geometry, BrickLink-friendly parts, collision-checked Studio build spec,
three size tiers, detailed interior, and a copy-ready Product Pack in every output level.
Real-Build Mode: ONStud Grid: ExactStudio: ValidateBOM: BrickLink XML
Designed for LEGO-legal museum fidelity: ≥8-stud width rule, tile-smooth bodywork, Technic spine, legal SNOT offsets,
and BrickLink Studio collision/connection validation (no intersections, no floating, no stressed parts).
Unique closed P538 built for the Duke of Aosta; final P538 constructed; chassis 262 914; introduced around the 1968 Turin Motor Show.
Known public appearances include 2005 Blackhawk Exhibition and 2006 Pebble Beach Concours d’Elegance; sold at Geneva auction in 1999 with ~9,000 km.
Powered by a Chevrolet V8 (commonly cited ~5.4L/327ci family) around 365 hp; 5-speed ZF transaxle referenced in period documentation.
P538 program cues: tubular chassis, fiberglass bodywork, independent suspension + disc brakes — all translated into LEGO-legal structural “spine + shell” planning.
Visual cues to preserve in LEGO form: low Kamm tail, canopy/roofline, wide front fender pods, deep side intakes, compact overhangs, clean prototype surfacing.
