Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new 5 Series Gran Turismo at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.

|---|---|---|---|
| 1 year | 12,000 mi | $205 | $17 |
| 3 years | 36,000 mi | $1,190 | $33 |

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 5 Series Gran Turismo is known for is N63 4.4 twin-turbo V8 oil consumption, valve stem seals, timing chain, turbos (550i GT) from about 60,000 miles ($3,000-$8,000+). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
F07 (US through 2017): 535i GT = N55 3.0T I6, 550i GT = N63 4.4 twin-turbo V8. Replaced by 6 Series GT. Timing chain. N63 V8 is high-maintenance (oil consumption/valve seals). Rear air suspension standard on GT. ZF 8-speed. Synthetic LL-01.
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 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.
