Lawyers at Shipman & Goodwin and Covington & Burling on Friday removed a breach-of-contract lawsuit against Darcars of Railroad Avenue Inc. to Connecticut District Court. The suit, filed by the Consumer Law Group, accuses the defendant of adding a commission of 2% to the price of new and used vehicles and selling vehicles for prices that are higher than those advertised by the defendant. Using alleged damages as an average across 1,100 putative class members, full damages are estimated by the plaintiffs to be at least $3 million.
