Buy here pay here ain't no joke. My uncle is setting up a BHPH dealer right now and will probably make a good bit of money if he does it right.
People with bad credit need cars too.
If you have the capability to own one or start one up, I'd say go for it. There is a demographic that will always be there to cater. I'd venture to say that MOST of the people will make the payments on time and it'll be fairly stress free. But the ones that do cause you problems, they will definitely be that headache.
I remember a fairly well to do person said that the best money making investment he had were trailer parks, because there was always that demographic looking for cheap places to live.
  Makes sense.
 shawty put $10k total on the car ($3000 down + 18 x 387) and has NOTHING to show for it...that is a hustle if I aint seen one
. best of both worlds would be to have a paid off car and lease something newer to drive around for luxury and travel with the money you save on that car note. Ain't nothing like bending your Space Jams flooring the newest benz/lexus
