The comparison page renders a year-by-year head-to-head table — for each model year (where both models have data), it shows complaint count or per-10K rate side by side and marks which model fares better that year. Buyers cross-shopping a specific model year should always check the year-level VinItel pages: vinitel.com/stats/nhtsa-complaints/genesis/g70/{year} and vinitel.com/stats/nhtsa-complaints/mercedes-benz/c300/{year}.

All complaint, crash, fire, and fatality data comes from the NHTSA Office of Defects Investigation (ODI) consumer-complaint database — the same source insurance regulators and the federal government use. NCAP star ratings come from NHTSA's New Car Assessment Program crash tests. Sales-volume normalization (per 10K sold) uses US annual vehicle sales. Data refreshes every 6 hours.
