According to personal circumstances. The store must have invested a lot, but it belongs to the business. After a long time, repeat customers can accumulate, provided that you have no problems in technology and management. Store can be bigger, can make a career, car locks can't. Novices can open small shops. After all, shops and cars are not the same concept. Opening a small shop is not necessarily more expensive than car investment. The advantage of the car is that many people go, but it belongs to tourists, similar to street stalls. I don't like it very much.
