car repair is looking more and more promising. the government requires drivers to have their cars inspected yearly, i think. so that might motivate drivers to get repairs before or after inspections.

In my zip code alone, there's about 11,000 car owners. I will serve about 5 zip code areas. the demand for auto repair must be high, especially during heavy weather seasons. I can even find estimates of a car's lifespan and use that to predict the number of car owners who'd be requesting repair services.

I should also study the supply though. How many auto repair stations or service providers are in my area? I was walking home and came across an auto repair station. They might be quite common. But since I'm focused on sole proprietorship and small business, I probably won't be much competition. Maybe I can approach auto repair service providers and make light partnerships with them.
