Question: how long do you have to wait to sell another car in gta 5?
Answer: You can sell a car to Los Santos Customs once per in-game day, which is every 48 minutes. Note that you always need to wait an entire 48 minutes between selling cars, so if you sold one at 9:03pm on one day, you couldn't then sell another car at 1am the next day: you would need to wait until 9:03pm.
