Sports car with advertising a valid deduction?

[Hunter Purnell]

Example. Buy a Corvette and put lettering on the back windshield “Will buy your house as-is for cash! Call xxx-xxx-xxxx” or make a website for people to fill out a form. I actually think this would be pretty good advertising. Also use the vehicle to look for deals and travel to meetings etc. 

 Has anyone done this? Any red flags from your accountant? I would think this would be fine as long as it’s used for business. And if used for personal only write off % used for business which I have done for a truck in the past.
