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 Hardtop 2 Door retires around 95,000 miles - but the exit window opens earlier here: Turbocharger failure risk window ($1,800-$3,000) opens ~90,000 mi. Carlyle's garage tracks this per car, against your actual odometer.
