Manual Data Extraction Guide for RockAuto.com

Since RockAuto has strong anti-bot measures, here's a manual approach to extract vehicle data:

1. Visit https://www.rockauto.com/
2. Click on "Catalog" in the navigation menu
3. You'll see a list of vehicle manufacturers (makes)
4. For each make, manually note down the models, years, and engines

This script provides a framework to input the manually collected data into your database.

        ================================================
        
        1. OPEN YOUR WEB BROWSER and go to: https://www.rockauto.com
        
        2. CLICK on the "Catalog" link in the navigation menu
        
        3. YOU WILL SEE a list of vehicle manufacturers (makes) like:
           - Acura
           - Audi
           - BMW
           - Chevrolet
           - Ford
           - Honda
           - Toyota
           - And many more...
        
        4. FOR EACH MANUFACTURER:
           a) Click on the manufacturer name
           b) You'll see a page with vehicle models organized by year
           c) Note down the models and years you see
           d) Example format: 2020 Honda Civic, 2019 Ford F-150, etc.
        
        5. TO FIND ENGINE INFORMATION:
           a) Click on a specific model/year combination
           b) You'll see parts categories for that vehicle
           c) Look for "Engine" or "Engine Mechanical" category
           d) Note down the engine type/specifications
        
        6. USE THE FOLLOWING COMMANDS to add data to your database:
        
        Example Python commands:
        >>> from manual_input import ManualDataInput
        >>> input_tool = ManualDataInput()
        >>> input_tool.add_vehicle_data("Toyota", "Camry", 2020, "2.5L 4-Cylinder")
        >>> input_tool.add_vehicle_data("Honda", "Civic", 2019, "1.5L Turbo")
        
        Or add multiple at once:
        >>> vehicles = [
        ...     {"make": "Ford", "model": "F-150", "year": 2021, "engine": "3.5L V6"},
        ...     {"make": "BMW", "model": "X3", "year": 2020, "engine": "2.0L 4-Cylinder Turbo"}
        ... ]
        >>> input_tool.add_multiple_vehicles(vehicles)
        
        7. TIPS FOR EFFICIENT DATA COLLECTION:
           - Focus on popular makes/models first
           - Record data in a spreadsheet as you go
           - Take screenshots of pages for reference
           - Be systematic - go alphabetically or by make popularity
