Use keywords and search criteria for specific vehicle features. A Craigslist saved-search can be setup for an email alert every time listings are posted that fits all search criteria.

- Category: Cars & Trucks
- For Sale: by Owner
- Max Year: 1997
- Fuel: diesel
- Transmission: manual
- Drive: 4wd
- Keywords: long bed

Even with zero results with these criteria, CL will email an alert once a fitting ad is listed.
