Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Avalon 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 | $148 | $12 |
| 3 years | 36,000 mi | $766 | $21 |
| 5 years | 60,000 mi | $1,562 | $26 |
| 7 years | 84,000 mi | $1,858 | $22 |
| 10 years | 120,000 mi | $3,721 | $31 |
| 15 years | 180,000 mi | $5,283 | $29 |
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.
Operator notes
Avalon discontinued after 2022. 3.5L 2GR-FKS V6, timing CHAIN (no belt). 0W-20 synthetic, 10,000-mi interval; severe service 5,000 mi. Very reliable with few chronic issues.
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 Avalon 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.
