Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Savana Cargo at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $125 | $10 |
| 3 years | 36,000 mi | $580 | $16 |
| 5 years | 60,000 mi | $1,530 | $26 |
| 7 years | 84,000 mi | $1,985 | $24 |
| 10 years | 120,000 mi | $3,390 | $28 |
| 15 years | 180,000 mi | $5,495 | $31 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
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
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, 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.
