ePER is especially useful for Fiat Auto Poland because many unique or regional parts were used in Polish-built models (e.g., specific engine variants, trim levels, or components for LPG-equipped cars sold in Eastern Europe).
While using unofficial mirrors is widespread in Poland, it is technically copyright infringement. Fiat/Stellantis owns this data. However, private, non-commercial use is generally tolerated as it helps maintain vehicles (good for brand loyalty). Do not host an ePer mirror publicly for profit. fiat+eper+polska
