Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new S90 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 | $158 | $13 |
| 3 years | 36,000 mi | $833 | $23 |
| 5 years | 60,000 mi | $1,841 | $31 |
| 7 years | 84,000 mi | $2,264 | $27 |

| 15 years | 180,000 mi | $6,388 | $35 |
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.
Operator notes
Base US S90 = B5/B6 2.0L Drive-E with 48V mild-hybrid (classified gas); T8 PHEV also offered separately. TIMING BELT engine (150k/12yr). 10,000-mi synthetic oil. Discontinued in US after MY2025 (globally may continue).
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 S90 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.
