Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Beyond the schedule, the first big-ticket item this ALPINA B8 Gran Coupe is known for is ALPINA 20-in tires from about 15,000 miles ($2,000-$3,000/set). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
G16 (8 Series Gran Coupe) based, 4.4L twin-turbo V8 (~613 hp), ZF 8HP ALPINA calibration. Final model year 2025 (no 2026 MY); last true Buchloe-built ALPINA before full BMW integration - 8 Series line ends ~April 2026. Relatively new so long-term data limited; expect shared 4.4L V8 issues. Timing CHAIN. Time-based service advised.
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 ALPINA B8 Gran Coupe retires around 95,000 miles - but the exit window opens earlier here: Hot-V coolant / turbo oil leaks risk window ($1,500-$4,000) opens ~50,000 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.
