eBay Motors Style make model year Search Integration within a store

I'm looking to enhance my eBay store with a search feature that allows users to filter products by make, model, and year only in my ebay store. This feature should be implemented as dropdowns in the item description. Make model and year will be searched in all of my listings in the title if possible or in the item description. (only in one, we need to select the best option)

Key Requirements:
- Implementation of dropdowns for make, model, and year
- Integration of this feature within my eBay store
- Has to meet ebay policy and rules.

Ideal Skills:
- Proficiency in eBay store customization
