Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new CLA-Class 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 | $335 | $28 |
| 3 years | 36,000 mi | $1,345 | $37 |
| 5 years | 60,000 mi | $3,180 | $53 |
| 7 years | 84,000 mi | $4,315 | $51 |
| 10 years | 120,000 mi | $6,360 | $53 |
| 15 years | 180,000 mi | $9,540 | $53 |
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 CLA-Class is known for is 8G/7G-DCT dual-clutch transmission (mechatronic/clutch) from about 60,000 miles ($2,500-$4,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Current-generation gas CLA (C118): 2.0L turbo-4 (some with 48V), 8G-DCT dual-clutch. FSS Service A/B; timing chain; synthetic oil ~10k/1yr. An all-new EV-first CLA ('EQ Technology', 800V, plus 1.5L 48V hybrid) launches for 2026 alongside the gas model; the profile here reflects the mainstream combustion CLA most common in rental fleets.
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 CLA-Class retires around 95,000 miles. 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.
