Cars

CG allows free ads, the seller of the car controls the data and the amount is based on what the seller can get the car financed for

It's an annoying feature, I have a car for sale as a private seller for cash only, yet the ad places a "monthly payment" next to it, I can see why it would be confusing for a buyer who is led to believe that the seller is taking payments. AFAIK it's just giving you a suggested monthly payment cost if you intend to finance the car - whether through the seller or your own bank.
