Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Galant 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 | $180 | $15 |
| 3 years | 36,000 mi | $840 | $23 |
| 5 years | 60,000 mi | $1,760 | $29 |
| 7 years | 84,000 mi | $2,180 | $26 |
| 10 years | 120,000 mi | $3,620 | $30 |
| 15 years | 180,000 mi | $5,280 | $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.
Beyond the schedule, the first big-ticket item this Galant is known for is 3.8L V6 timing belt (Ralliart) from about 60,000 miles ($700-1,200). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
9th-gen Galant ended in the US after 2012. 2.4L 4-cyl (4G69/4B11-class) with TIMING CHAIN paired to a 4-speed automatic; Ralliart 3.8L 6G75 V6 uses a TIMING BELT at 60,000 mi. Era schedule: 3,750 severe / 7,500 normal oil. Aging car: treat rubber, hoses, and the dated 4-speed auto as wear items.
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 Galant retires around 95,000 miles - but the exit window opens earlier here: 3.8L V6 timing belt (Ralliart) risk window ($700-1,200) 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.
