When the smart money sells
On fleet math, a gas 5 Series Gran Turismo retires around 95,000 miles - but the exit window opens earlier here: N63 4.4 twin-turbo V8 oil consumption, valve stem seals, timing chain, turbos (550i GT) risk window ($3,000-$8,000+) opens ~60,000 mi. 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.
