We provide customers with a full range of related products and services, including the appraisal and purchase of vehicles directly from consumers; the financing of vehicle purchases through CAF and third-party financing providers; the sale of extended protection plan (“EPP”) products, which include extended service plans (“ESPs”) and guaranteed asset protection (“GAP”); and vehicle repair service. Vehicles purchased through the appraisal process that do not meet our retail standards are sold to licensed dealers through on-site wholesale auctions.
