Data Sources & Methodology
Complaints: NHTSA Office of Defects Investigation consumer complaint database (296 records for this model). Public domain data, updated monthly.
Sales data: Not yet available for this model. Complaint counts are shown as raw numbers.
On-road outcomes: Accident, title-brand, theft and odometer records for 1,715 BMW Z3 VINs in our vehicle-history database. Independent of the NHTSA complaint file — a complaint is what an owner reported, these are what was recorded against the vehicle. Year-level figures are shown only for model years with at least 200 VINs on record.
Rate calculation: Complaints per 10,000 vehicles sold = (complaint count / US annual sales) x 10,000. This normalizes for sales volume so high-volume models like Civic or Camry aren't unfairly penalized.
Year classifications: AVOID = 1.5x+ the model's median complaint count. GOOD = 0.6x or below. Years less than 3 years old are marked TOO NEW (insufficient data).
