He will sell it if it is on a buy-here Pay-here basis... Someone who is willing to put 600 down (which is more than what they have in it) and who is willing to make payments of $54.00 per week will snatch it up. It will probably break down in 2 weeks... Get repoed, fixed, re-sold and the cycle continues.
I know a guy who has a car lot and laughs about the number of times he sells the same vehicle. He buys them at the sale for $300-$400, brings them to the lot, dopes them up and then sells them over and over again. He sells to people he KNOWS won't pay for it so he can go get it and sell it again. He says eventually someone will trash it before it gets repoed, and then he junks it for parts. He says that he makes thousands of dollars over the life of a vehicle that he only has 300.00 tied up in.
Buy-here Pay-here customers will buy ANYTHING as long as they can ride RIGHT NOW...
