Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new IS 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 | $215 | $18 |
| 3 years | 36,000 mi | $1,040 | $29 |
| 5 years | 60,000 mi | $2,590 | $43 |
| 7 years | 84,000 mi | $3,020 | $36 |
| 10 years | 120,000 mi | $5,930 | $49 |
| 15 years | 180,000 mi | $8,520 | $47 |
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.

When the smart money sells

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.
