I have a friend who works in the used car business. Once, he seriously told me about a "business." A luxury car bought for 100,000, soaked in water, with a bit of a story. Repair it, with a cost of 150,000. Listed at 600,000. He said the process is very simple. First, find a girl with good conditions to date. In the early stage, transfer money to her to buy bags, phones, etc., using transfers without notes. Once the relationship is "in place," take her to a car dealership. He said he would buy her a car.
