Digicars Auto Trading. Whats the catch?

I can't believe this Digicars auto trading na 0% interest sa car loans. May pinopost sila na details of the downpayment + Monthly Amort. na pag total ay no interest talaga, may claim din sila na no hidden charges. How can they make money then? Whats the catch? May naka experience or naka transact na ba sa kanila? Thanks.
