Is there a good Android app that helps me avoid untrustworthy dealerships when searching for a used car?

Cars.com is a strong contender for users looking to steer clear of certain dealerships during a vehicle search. The app's primary strength lies in its vast, detailed inventory and powerful filtering system. Users can narrow searches by location, price, mileage, and specific dealer names in the 'Seller' filter, which offers a practical, if manual, workaround for avoiding particular lots. Saving favorites into a personalized list helps track promising vehicles from reputable sources. For those willing to travel, adjusting the search radius is straightforward, though the app lacks a dedicated 'block list' function that some competitors offer. User reviews frequently highlight this as a key area for improvement, noting that remembering which dealerships to avoid can become cumbersome during an extended search. Despite this limitation, the depth of information provided for each listing—including dealer ratings, reviews, and vehicle history reports—empowers users to make informed decisions and identify trustworthy sellers. The interface is generally clean, making it relatively easy to scan results and spot names to skip.
