AutoTrader.com is adding features to its database of more than 3 million cars so users can further customize their choices.

The additions include additional keyword search and features checklist functionality. For example, buyers can search for 11 specific features such as “handicapped accessible” or “leather interior.”

Buyers can also now search for cars by vehicle series and class.

The features appear when users enter a zip code under “Find Your Car.”
