Kind of in the business.

Those used car dealers you see pop out of nowhere with many nice cars available for sale? Those are money laundering business. Many of them are run by former underworld bosses. They wash their hands and start "clean" business as a used car dealership. Bulk of their profits are actually from the shop loans they give out to buyers. The interest on those loans are close to exorbitant.

The bootstrap companies normally start very small. They purchase really bad cars then fix them up to a saleable state and sell them for a profit. Example, 8k for a run down myvi. Put in a few thousand to repair and touch up. Then sell it for a few grand profit. Normally myvi, wira, saga are the most popular ones. As you make money, you get better vehicles to sell like pick up trucks and C segment cars.

There are used car dealers that get bank loans as well. They operate just like regular car dealers.
