Built an end-to-end used-car pricing analysis for VW and Audi listings: combined the datasets, explored price and mileage patterns, engineered predictive features, and compared Linear Regression against Random Forest using R², MAE, and RMSE. The work culminated in a clear CPO pricing recommendation grounded in model performance and feature importance.
