Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new A5 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 | $220 | $18 |
| 3 years | 36,000 mi | $1,110 | $31 |
| 5 years | 60,000 mi | $3,140 | $52 |
| 7 years | 84,000 mi | $4,320 | $51 |
| 10 years | 120,000 mi | $6,280 | $52 |
| 15 years | 180,000 mi | $9,420 | $52 |
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 A5 is known for is Dual-clutch (S tronic) / mechatronic from about 90,000 miles ($2,000-$3,600). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
All-new A5 (PPC platform) that replaces the A4 in the US for 2025; liftback/Sportback body marketed as sedan. 2.0T with timing CHAIN. Long-term reliability data still limited. 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 A5 retires around 95,000 miles - but the exit window opens earlier here: Dual-clutch (S tronic) / mechatronic risk window ($2,000-$3,600) opens ~90,000 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.
