Disclaimer:Labor rates are sourced from U.S. Bureau of Labor Statistics wage data by metro area. Parts costs and labor-hours estimates (how long a job is expected to take) are internal editorial figures, not pulled from an industry-standard labor-time guide or a published parts-pricing database, and not verified against real shop quotes. We checked this directly against a competitor's published estimates across 11 of 12 repair types on 3 vehicles: most repair categories (water pump, starter motor, catalytic converter, alternator, radiator, AC compressor, and timing chain work) were originally found to run significantly below real-world pricing, by roughly 1.2x to 4.3x depending on the specific repair and vehicle. All seven of those categories have since been re-sourced with real, verified figures. Simpler jobs (oil changes, belts, batteries) landed close to real-world pricing on the vehicles checked so far.
