A ProoV case study · educational project, not employment

Built an end-to-end used-car pricing analysis for VW and Audi listings: combined the datasets, explored price and mileage distributions, examined correlations and brand differences, and compared Linear Regression against Random Forest using R², MAE, and RMSE. The work also translated model output into a practical CPO pricing recommendation with a human-in-the-loop review threshold.
