I had my fair share of time in management roles at an auto dealership. If you dig through his mumble speak, its 78 n' 3 months (not 783).
(If this isnt a joke skit all the way around.) 78 Months sounds normal, and 84 months sounds normal. But that three months being said by itself is odd. Looking at the presentation of the car and the 19 year old mixed kid telling the wanksta what to say - It's obviously an independent lot. Which they have some fucking garbage rules with banks mandating that if the client defaults on the car within a certain time period, then the loan is void and it essentially falls on the dealership to repo the vehicle (Santander, Westlake, Carolina, etc.) Its been a while since Ive worked at one, but I cant imagine the companies have changed all that much.
Going a step further, and looking at the price of the car with 0 down. Knowing that its likely a high interest rate. Guessing the model range of the AMG... The car is probably a salvaged title. Which would explain even further the secondary credit company, and possibly their stipulations. If he's at 27.99% interest over 78 months, thats about a ~10,000 dollar LOAN AMOUNT for an AMG for reference. The first three months is probably a small payment plan with the dealership, thats likely
more than $300/m. Making the car even more questionable, as not only its salvage title.. but how many fucking miles does this thing have?
If the guy was a reputable buyer, on a solid vehicle at a good dealership - the finance company would break even somewhere around 2 and a half years into the loan at these numbers. But they probably arent even expecting to receive the loan. The car probably has three tracking devices on it, and it'll be picked up the first day its late. The dealership itself probably makes more than it would cost to repo on the second months payment because they repo their own vehicles. If they repo it, they condition it back to "passable" and rinse/repeat - hoping to hook line and sink another wanksta.
