Proof of Usefulness Score
You're In Business

OnlineCarStereo.com is a legitimate, long-standing e-commerce business (est. 1999) with verifiable traffic (~250k global rank) and revenue. However, the project submission is extremely poor, containing exaggerated claims ('most people have used my product') and confusing data ('marketcap' for revenue). While the business has high real-world utility as a retailer, it lacks technical innovation (standard e-commerce), faces mixed reputation regarding service quality ('shady' reviews vs. loyal buyers), and operates in a mature/declining market niche. The low score reflects the lack of novelty, poor submission quality, and the disconnect between the claimed 'everyone' audience and the niche reality.
