Proof of Usefulness Score
Industry Mainstay

CarOnSale is a highly established B2B automotive marketplace with significant verified traction (Series C funding of ~$160M, estimated $83M revenue, ~200 employees), contrasting sharply with the low-quality submission provided. While the user input contained vague and inaccurate claims (e.g., 'most people have used my product'), external verification confirms it is a market leader in Germany expanding across Europe. The score reflects its massive real-world utility and scale (400-700 range), penalized significantly for the poor quality of the submission data.
