LLM car pricing engine fails in Nigeria due to outdated training data

A developer building AutoValue, a Nigerian used-car valuation platform, found that LLMs consistently priced cars at ₦20-25 million because their training data reflected a naira-to-dollar rate of ₦450, not the current ₦1,500. The fix involved using live web search for base prices and limiting the LLM to adjustments only. This highlights a general risk for LLM products in volatile economies.
