A midsize luxury crossover SUV with a gas powertrain. Below: the service intervals with real cost ranges, the repairs RX owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

When the smart money sells
On fleet math, a gas RX 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.
