When the smart money sells

On fleet math, a gas S90 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.
