What Gracy demonstrated

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 with Random Forest using R² and MAE. The work culminated in a practical CPO recommendation to use the Random Forest model, backed by feature-importance insights and a business impact estimate.
