Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Legacy 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 | $170 | $14 |
| 3 years | 36,000 mi | $785 | $22 |
| 5 years | 60,000 mi | $1,760 | $29 |
| 7 years | 84,000 mi | $2,100 | $25 |
| 10 years | 120,000 mi | $3,820 | $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 Legacy is known for is Turbo (XT models) / oil consumption from about 60,000 miles ($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
DISCONTINUED after 2025 (final Legacy built Sept 2025). 2.5L FB25 or 2.4L FA24 turbo (XT), CVT, timing CHAIN. Full-synthetic oil 6,000 mi/6 mo; severe 3,000-3,750 mi. Spark plugs 60k; long-life coolant ~137,500 mi. XT models recommend premium fuel.
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 Legacy retires around 95,000 miles - but the exit window opens earlier here: CVT service/repair risk window ($4,000-7,500) opens ~70,000 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.
