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 B6 Gran Coupe is known for is ALPINA staggered 20-in tires (performance) from about 15,000 miles ($1,800-$2,800/set). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
F06-based ALPINA (6 Series Gran Coupe body), N63TU 4.4L twin-turbo V8 (~600 hp), ZF 8HP with ALPINA calibration. Discontinued in US with the F06 6 Series after MY2019. Timing CHAIN. ALPINA service costs run well above standard BMW; specialist tires/fluids. Best serviced on time (12 mo) even at low mileage.
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 B6 Gran Coupe retires around 95,000 miles - but the exit window opens earlier here: N63 oil consumption / valve stem seals risk window ($3,500-$5,500) 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.
