Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new EQS 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 | $0 | $0 |
| 3 years | 36,000 mi | $765 | $21 |
| 5 years | 60,000 mi | $2,105 | $35 |
| 7 years | 84,000 mi | $2,870 | $34 |
| 10 years | 120,000 mi | $4,475 | $37 |
| 15 years | 180,000 mi | $7,080 | $39 |
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 EQS is known for is Airmatic air suspension (standard) from about 60,000 miles ($2,000-$5,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
V297 all-electric full-size flagship sedan (EQS SUV shares platform). EV - NO oil changes; tires, cabin filter, brake fluid (~2yr), long-interval battery coolant. Standard Airmatic air suspension and rear-axle steering are the big-ticket mechanical wear items; Hyperscreen software is the top complaint source. Regen braking extends pad life. Battery warranty 10yr/155k mi.
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 battery-electric EQS retires around 150,000 miles - but the exit window opens earlier here: Airmatic air suspension (standard) risk window ($2,000-$5,000) 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.
