Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Express 2500 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 | $110 | $9 |
| 3 years | 36,000 mi | $575 | $16 |
| 5 years | 60,000 mi | $1,375 | $23 |
| 7 years | 84,000 mi | $1,840 | $22 |
| 10 years | 120,000 mi | $3,435 | $29 |
| 15 years | 180,000 mi | $5,170 | $29 |
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.
Beyond the schedule, the first big-ticket item this Express 2500 is known for is Transmission strain under load ($1,500-$3,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
2500 is the 3/4-ton Express, frequently ordered with the 6.6L L8T gas V8. Same durable GMT610 platform, timing CHAIN, and 8L90 8-speed as the base Express, but the heavier GVWR means more frequent brake service and severe-schedule fluids under load. Diesel option discontinued; gas only for 2025.
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 Express 2500 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.
