A judge has ordered Mercedes-Benz USA LLC to pay $482,000 in damages and legal fees to a Wisconsin customer who was sold a defective car and not given a refund on time.

Vince Megna, a Milwaukee lawyer who represents the customer, said he believes the judgment is the largest involving a single car under a state “lemon law,” which protects consumers who are sold junk cars. The judge was expected to sign the final order as early as Friday.
