GMC C1500: Classic truck market highly condition-dependent. 454 big-block commands premium over small-block variants. Actual mileage varies wildly (many odometers rolled over multiple times or replaced). Rust-free Southern examples bring top dollar. Project-grade trucks start around $5k-8k; restored/low-mile examples can exceed $30k. Market strengthened 2020-2025 for square-body GM trucks.

AI-estimated US used-market price range. LOW = private-party, base trim, typical mileage. HIGH = dealer retail (Carvana/CarMax), desirable trim, below-average mileage. Local prices vary ±20% with condition, mileage, and region. Treat as a ballpark, not a quote.
