Our Review Methodology

How We Research & Test

At Project JDM, every review, buyer guide, and comparison is based on genuine hands-on research, deep community knowledge, and first-hand testing where possible. We never accept payment to alter our ratings or recommendations.

Our Evaluation Criteria

We score JDM vehicles, parts, and services across five weighted dimensions:

Criteria	Weight	What We Measure
Reliability	30%	Long-term dependability, known failure points, maintenance costs
Performance	25%	Engine output, handling, real-world driving dynamics
Value	20%	Purchase price vs. ownership cost, parts availability
Authenticity	15%	Factory spec, matching numbers, import documentation
Community Consensus	10%	Forum reputation, owner satisfaction over time

Our Review Process

1. Community Research — We aggregate opinions from JDM forums, owner clubs, and enthusiast communities
2. Specification Analysis — We cross-reference factory specs, USDM differences, and compliance requirements
3. Expert Consultation — We consult with JDM importers, mechanics, and long-term owners
4. Cost Modeling — We calculate real total cost of ownership including import, compliance, and parts
5. Final Scoring — Weighted scores across our 5 criteria with transparent breakdowns

Editorial Independence
