Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new M4 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 | $275 | $23 |
| 3 years | 36,000 mi | $1,340 | $37 |
| 5 years | 60,000 mi | $3,690 | $62 |
| 7 years | 84,000 mi | $4,665 | $56 |
| 10 years | 120,000 mi | $7,380 | $62 |
| 15 years | 180,000 mi | $11,070 | $62 |
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 M4 is known for is Steel M brake + tire wear from about 20,000 miles ($1,500-$3,000 per axle). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
G82 M4, S58 twin-turbo I6 (shared with M3/M2). RWD manual or xDrive 8-speed auto. One-piece crank hub, timing CHAIN, plugs ~40k. CBS telematics; owners often shorten oil to 5,000-7,500 mi for track use.
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 M4 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.
