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.

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

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 IS 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.
