Provenance and originality
Start with identity, paperwork and originality. For the Lamborghini Miura, the strongest cars have a continuous ownership file, matching numbers where applicable, original manuals, invoices and evidence of work by recognised marque specialists. Polo Storico-style provenance, matching numbers, original colour, separated sump (SV only), front-pivoted door hinges (late) and continuous history matter sharply.
