Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new X7 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 | $225 | $19 |
| 3 years | 36,000 mi | $765 | $21 |
| 5 years | 60,000 mi | $2,305 | $38 |
| 7 years | 84,000 mi | $2,895 | $34 |
| 10 years | 120,000 mi | $4,970 | $41 |
| 15 years | 180,000 mi | $7,275 | $40 |
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 X7 is known for is Valve stem seals / oil consumption (V8 M60i hot-vee) from about 60,000 miles ($3,000-$6,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Timing chain. G07 LCI. xDrive40i = B58 3.0L turbo I6; M60i = S68 4.4L twin-turbo V8 (48V mild hybrid). Standard air suspension both axles - budget for it as the signature X7 wear item. Condition Based Service.
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 X7 retires around 95,000 miles - but the exit window opens earlier here: Valve stem seals / oil consumption (V8 M60i hot-vee) risk window ($3,000-$6,000) opens ~60,000 mi. 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.
