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

What stood out6
- Combined VW and Audi listings into a single analysis frame and used brand-aware visualizations to compare market behavior.
- Identified and removed clearly invalid rows such as zero engine-size and extreme price outliers before modeling.
- Built and compared both Linear Regression and Random Forest models, then communicated the performance gap using R², MAE, and RMSE.
- Translated model output into a CPO-oriented recommendation with an explicit pricing-risk narrative.
- Exploratory Data Analysis
- Leakage-Free Feature Preparation
