Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new C70 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 | $125 | $10 |
| 3 years | 36,000 mi | $835 | $23 |
| 5 years | 60,000 mi | $1,670 | $28 |
| 7 years | 84,000 mi | $2,140 | $25 |

| 15 years | 180,000 mi | $5,715 | $32 |
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 C70 is known for is Retractable hardtop mechanism failure from about 60,000 miles ($500-$2,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.

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 C70 retires around 95,000 miles - but the exit window opens earlier here: Retractable hardtop mechanism failure risk window ($500-$2,500) 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.
