Known repair windows
What Mustang owners actually run into

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Mustang 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 | $115 | $10 |
| 3 years | 36,000 mi | $610 | $17 |
| 5 years | 60,000 mi | $1,685 | $28 |
| 7 years | 84,000 mi | $2,030 | $24 |
| 10 years | 120,000 mi | $3,895 | $32 |
| 15 years | 180,000 mi | $5,580 | $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.
Beyond the schedule, the first big-ticket item this Mustang is known for is Turbocharger wear / wastegate from about 80,000 miles ($1,500-$2,800). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
In production (S650, 7th gen). Base engine 2.3L turbo EcoBoost I4 (~315 hp); GT gets 5.0L V8. Full synthetic; Ford IOLM ~10k normal, 5k track/severe. Timing chain (no belt). 10R80 10-speed auto or 6-speed manual. Reset IOLM after each change.
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 Mustang 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.
