Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new A7 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 | $250 | $21 |
| 3 years | 36,000 mi | $1,215 | $34 |
| 5 years | 60,000 mi | $3,640 | $61 |
| 7 years | 84,000 mi | $4,765 | $57 |
| 10 years | 120,000 mi | $7,280 | $61 |
| 15 years | 180,000 mi | $10,920 | $61 |
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 A7 is known for is Adaptive air suspension from about 80,000 miles ($1,500-$2,800). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
C8 A7 Sportback, 3.0T V6 55 TFSI mild hybrid, ZF 8-speed, timing CHAIN. 2025 is the FINAL US year for A7/S7 (discontinued for 2026; only RS7 continues, and the new A6 Sportback assumes the role). 10k-mi synthetic oil.
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 A7 retires around 95,000 miles - but the exit window opens earlier here: Adaptive air suspension risk window ($1,500-$2,800) opens ~80,000 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.
