Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new IS F 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 | $350 | $29 |
| 3 years | 36,000 mi | $2,250 | $63 |
| 5 years | 60,000 mi | $5,200 | $87 |
| 7 years | 84,000 mi | $6,125 | $73 |
| 10 years | 120,000 mi | $11,300 | $94 |
| 15 years | 180,000 mi | $17,400 | $97 |
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 IS F is known for is Brembo brakes + performance tires (consumables) ($1,500-$3,000 brakes; $1,200+ tires/set). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Final model year 2014. Naturally aspirated 5.0L V8 (2UR-GSE), 8-speed auto, timing chain. High oil capacity (~9-10 qt); 5k synthetic intervals. Track use shortens brake/tire/fluid life. Drivetrain generally robust; consumables are the main cost.
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 F 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.
