Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new LS 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 | $270 | $23 |
| 3 years | 36,000 mi | $1,290 | $36 |
| 5 years | 60,000 mi | $3,220 | $54 |
| 7 years | 84,000 mi | $3,760 | $45 |
| 10 years | 120,000 mi | $7,340 | $61 |
| 15 years | 180,000 mi | $10,560 | $59 |
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 LS is known for is Air suspension components (compressor/struts) ($1,200-$3,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Flagship sedan; 2026 latest (incl. LS 500 AWD Heritage Edition). LS 500 = 3.5L twin-turbo V6 (V35A-FTS); LS 500h = 3.5 V6 multi-stage hybrid. Timing chain. 0W-20 synthetic, 10k/12mo. Air suspension is the main big-ticket wear item.
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 LS 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.
