Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Corolla iM 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 | $90 | $8 |
| 3 years | 36,000 mi | $440 | $12 |
| 5 years | 60,000 mi | $930 | $16 |
| 7 years | 84,000 mi | $1,160 | $14 |

| 15 years | 180,000 mi | $3,010 | $17 |
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 Corolla iM is known for is CVT (K313 belt-type) hesitation/failure from about 80,000 miles ($3,000-4,500 replacement). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Timing chain. 1.8L 2ZR-FAE (Valvematic), 6MT or belt-type CVT. Final US year 2018 (was Scion iM 2016; replaced by Corolla Hatchback for 2019). 0W-20 synthetic 10k normal; change CVT fluid ~60k severe. Mild oil consumption at high mileage - monitor level.
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 Corolla iM retires around 95,000 miles - but the exit window opens earlier here: CVT (K313 belt-type) hesitation/failure risk window ($3,000-4,500 replacement) 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.
