911 maintenance cost: 5 and 10 years
| Period | Miles | Estimate | Basis |
|---|---|---|---|
| Per year | 15,000 | $1,974 | Porsche plan, years 2–5 ÷ 4 |
| 5 years | 75,000 | $7,895 | Years 2–5 plan MSRP (year 1 included) |
| 10 years (floor) | 150,000 | $15,790+ | Porsche's years 2–5 plan cost, repeated |
Method: Porsche's own Service Maintenance Plan MSRP for years 2–5 (Plus One $1,850; Plus Two $1,905; Plus Three $3,030; Plus Four $1,110) totals $7,895; the year-1 service is included with a new car. ÷ 4 years = per year. Scheduled maintenance only: tires and repairs are extra. AAA has no sports-car category. The 10-year figure is a floor: it doesn't add the larger age-related repairs (and later scheduled items such as spark plugs or coolant) that come after year 5.
How the verdict is set: Two inputs. Cost: the estimate against AAA's $1,656 all-vehicle average (more than 3% under counts in the car's favor, more than 3% over against it). Complaints: NHTSA owner complaints per 1,000 sold against the median of every model in our study (0.48); well under the median helps, well over hurts, roughly double or more hurts twice as much. Both low = "No"; both high = "Yes". Models without a dollar estimate get no verdict.

- Most-reported systems: electrical system (1,435).
Complaints measure problems owners reported to the government, not repair bills: a high count signals more unscheduled repairs, which AAA's category benchmark doesn't adjust for. 911 years to avoid →
