Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new AMG GT 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 | $550 | $46 |
| 3 years | 36,000 mi | $2,450 | $68 |
| 5 years | 60,000 mi | $6,600 | $110 |
| 7 years | 84,000 mi | $9,400 | $112 |
| 10 years | 120,000 mi | $14,100 | $118 |
| 15 years | 180,000 mi | $20,700 | $115 |
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 AMG GT is known for is Staggered performance tires from about 10,000 miles ($1,500-$2,800/set). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
C192 generation (2024-2025). Primarily gas 4.0L twin-turbo V8 (GT 55/63/63 Pro); GT 43 uses a 2.0L turbo-4, and GT 63 S E Performance is a 805-hp plug-in hybrid variant. Exotic/AMG service is largely time-based and premium-priced; annual minor service and biennial major service run high. Brake fluid annually if tracked. Timing chain (no belt).
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 AMG GT retires around 95,000 miles - but the exit window opens earlier here: Carbon-ceramic brake replacement (if equipped) risk window ($10,000-$15,000) opens ~20,000 mi. 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.
