Used Vehicle Pricing & Valuation Model

Regression case study using feature engineering and tree ensembles on cross-country car listings.

Built a regression model to predict used car prices across 8 countries using 100K listings. Cleaned outliers, engineered features, and tuned tree-based models (Random Forest, Gradient Boosting) to reach R² = 0.867 and MAE ≈ €2,660.

Key Outcomes

R² = 0.867
MAE ≈ EUR 2,660
100K listings across 8 countries
