When the smart money sells
On fleet math, a gas ALPINA B7 retires around 95,000 miles - but the exit window opens earlier here: N63TU3 oil consumption / valve stem seals risk window ($3,500-$5,500) 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.
