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.

What stood out6
- Combined VW and Audi listings with a brand label and used that structure consistently across EDA and modeling.
- Identified the strongest price relationships and supported them with concrete observations, including the Audi price premium.
- Compared Linear Regression against Random Forest using multiple metrics and selected the stronger model for the CPO use case.
- Translated model performance into a business impact statement and a clear recommendation for the pricing team.
