WALTHAM, Mass. — Through a new partnership, DealerRater’s more than 450,000 dealer reviews will now be accessible through CarZen’s Apple iPad app.

The CarZen app offers car shoppers a dealer locator, and allows the, to browse and search through more than two million new- and used-car listings, according to the company.

“We are excited to collaborate with CarZen to feature car dealer reviews on the newest version of its iPad app,” said Chip Grueter, president of DealerRater. “When shopping for a car, third-party reviews on dealerships are an integral part of the car-buying experience, and we are happy to share the reviews of our DealerRater community members with the fast-growing iPad market that CarZen serves.”

The CarZen app recently passed 120,000 downloads, less than 6 months after it was made available to car shoppers on the Apple App Store.

“Our mission is to serve our users with the highest quality experience possible,” said Nick Gidwani, CEO of CarZen. “By offering DealerRater’s nearly half a million reviews of dealers — and not hiding bad reviews — we are providing our users with great content and ultimate transparency when searching for a car.”
