MINEOLA, N.Y. The law firm that filed a $350 million antitrust lawsuit against Carfax now represents over 700 dealership plaintiffs — up from just 124 when the suit was originally filed in May 2013.

Bellavia Blatt Andron & Crossett, P.C. alleges that Carfax has illegal alliances with key players in the auto industry, which freezes out competition, thereby resulting in increased prices and unreliable vehicle history reports. According to the firm’s officials, dealers are forced to do business with Carfax at grossly inflated prices, only to have Carfax spend these inflated revenues on ads that disparage dealers as dishonest.

“The number of participating dealers in this suit continues to grow on a weekly basis,” said Bellavia Blatt Senior Partner Leonard A. Bellavia. “This is a testament to just how important this case is to their future business dealings.”
