Yes. And it is not by buying and selling used cars.
First - in most jurisdictions, you need to have a special permit to sell more than 2 cars a year, and there are rules about storing un-tagged/registered cars.
So think again: What are you interested in? It would be a shame to start a company (for example a 'call selling' company, and then discover...one year into it...after you have spent a lot of money...that you HATE selling cars to people...you ABSOLUTELY HATE the idea of selling one more car....but you have 50 of them.
Yes...bad thought isn't it?
Instead, sit down and make a list of all the kind of jobs that you think you can tolerate doing every day for a year. then from that list make a list of the ones you can tolerate for 5 years...then ten years. Take that short list of 10 year jobs and go to the BLS (Bureau of Labor and Statistics) websites and see what industries those jobs are in...and THAT will tell you what kind of business to start.
You can also check helpful websites like Excellence-Success, Upwork and Fiverr for business ideas, business plans and marketing - but make a quick trip to the BLS web pages because there you can get a sense of how much you can EARN...and that is important.
