Car Price Prediction
π Car Price Prediction: Predicting Used Car Prices with Machine Learning
π Project Overview
Buying or selling a used car can be challenging, especially when it comes to determining the right price. A carβs price depends on multiple factors such as its brand, model, year of manufacture, fuel type, transmission, mileage, and condition.
This project aims to solve this problem by building a Machine Learning-powered Car Price Prediction System that provides accurate price estimates based on historical data.
This web-based application helps both car buyers and sellers make informed decisions by predicting the fair market value of a used vehicle. Instead of relying on guesswork or inconsistent price listings, users can simply enter a few details about the car and get an instant price prediction backed by data.

π How Does It Work?
The project uses Supervised Machine Learning Algorithms to analyze past sales data and learn the pricing patterns. Hereβs the complete workflow:
1οΈβ£ Data Collection & Cleaning
- I scraped a large dataset from a website using Python and Selenium. It contain features like brand, model, manufacturing year, mileage, fuel type, engine size, location, and selling price.
- The dataset was cleaned by handling missing values, removing duplicates, and normalizing text data.
2οΈβ£ Model Selection & Training
- Various regression models were trained and tested, including:
- β Linear Regression β For a simple price trend analysis.
- β Random Forest Regressor β To capture complex relationships between features.
- β Gradient Boosting Regressor β To improve prediction accuracy.
- After evaluating different models, Gradient Boosting was chosen for deployment due to its high accuracy and stability.
3οΈβ£ Web Application Development
- A user-friendly web interface was built using Flask.
- Users can enter car details in a simple form and instantly get a predicted price.
4οΈβ£ Deployment
- The model and web application were deployed on Render for easy access.
- Now, users can predict car prices from any device with an internet connection.
