My car broke down recently and I need to buy another one, but I can't afford to buy one right now. I'd have to lease or finance, but I have a business credit card that has 0 APR for a year, so if I could charge a car on that card it would save me a lot of trouble. I do need a car for work everyday so it would be used for business purposes; I'm just not sure if I'm allowed to charge one on my business card since it would also be used for personal reasons.
Note: I own a sole proprietorship. I'm not working for someone else. The business card is mine.

Don't do it unless you want to lose your job and possibly go to jail.
