CarStory released its monthly Used Vehicle Deal Alert on Wednesday, highlighting the best deals it’s seeing for its customers across the country.

On the reverse side, however, is something particularly useful for dealers: the top five most popular used vehicles searched for on CarStory's site.

Here’s the list, based on online searches by make and model, according to CarStory:

CarStory's Top Five Most-Popular Used Vehicles

• Ford F-150 
• Jeep Wrangler 
• Ford Mustang 
• Cadillac Escalade 
• Audi A4

The report from CarStory outlines the best used-vehicle deals it can find around the country that are listed on its site, saying that the average savings across the country comes in at $3,039, or 17 percent per vehicle. The top three were on the Toyota Prius (in Los Angeles), the BMW 5 Series (in Phoenix) and the Mercedes-Benz C-class (also in Los Angeles).

“With so much information out there, finding the best deals on used cars can be challenging for consumers,” said Chad Bockius, the company’s chief marketing officer. “Our CarStory Deal Alerts analyze millions of pieces of pricing data to help consumers cut through the digital noise and save dollars this holiday season, while also giving them a snapshot of what other consumers are searching for.”

After L.A., Philadelphia has the second-highest average discount on used vehicles listed on CarStory.

Brand-by-brand, Mercedes-Benz vehicles are discounted in the most cities (13) according to CarStory, followed by Jeep (11), Nissan (6), Chevrolet (4) and Lexus (4).
