A recent Court of Appeal ruling has opened the door for motorists to seek compensation from car finance companies due to undisclosed commissions. Marcus Johnson, a claimant from Wales, discovered that his dealership received a 25% commission on his financing agreement, totaling over £1,650. The ruling declared such secret commissions unlawful, prompting the finance industry to set aside funds for potential claims. Experts advise affected consumers to lodge their complaints promptly, checking finance agreements for undisclosed fees. However, ongoing legal challenges may delay claims processing.
