What Liberty owners actually run into

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Liberty 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 | $332 | $28 |
| 3 years | 36,000 mi | $1,621 | $45 |
| 5 years | 60,000 mi | $3,510 | $59 |
| 7 years | 84,000 mi | $4,174 | $50 |
| 10 years | 120,000 mi | $7,595 | $63 |
| 15 years | 180,000 mi | $11,105 | $62 |
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
Final KK-generation year; 3.7 PowerTech V6 (timing CHAIN), 42RLE 4-speed auto. Era manual: 3,000 mi oil severe / 6,000-7,500 normal. At this age, prioritize rubber hoses, fuel lines, seals and rust in addition to the schedule.
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 Liberty 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.
