Operator notes
Cargo variant of the Savana; same GMT610 platform. GAS ONLY (4.3L V6 / 6.6L L8T V8), 8-speed auto since 2023; 2.8L Duramax diesel discontinued after 2022. Timing CHAIN. Commercial/severe-service schedule (short trips, heavy loads) shortens oil, trans, and brake intervals.
When the smart money sells
On fleet math, a gas Savana Cargo retires around 95,000 miles. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
