Real-Build Substitution Note

Some rendered images may show colors or finishes (chrome, metallic, etc.) that are not currently produced by LEGO. Substitution notes are included for real-world building.

BrickLink/Studio workflow: Use the Printable BOM as your shopping list; verify color availability and swap per the substitution table. Build chassis + wheel boxes first, then skin.
