Google is testing a new service for local car dealership inventory. They are yet to comment on this but it only appears to be live in the US at this time.
When you visit google.com/local/cars you can see a list of cars that are available at local dealerships. You can filter the results by things such as new or used; brand and type. These filters aren’t 100% correct yet, but this isn’t such an issue since it’s clearly still in testing. In the car listings you can see full details and specifications on the vehicles, you can also enlarge images for a closer look.
This tool appears to be in the very early testing stages. However, if it passes testing this could be a great tool for local dealerships.
