Business & farm

Person 2 says because the car is owned by the LLC, everything that they do is expensed 100% to the business.  Because they have a second car for personal use, their first car thats owned by the business is all able to be written off (actual expenses).

 

Person 1 also says that they use one of the cars strictly for business.  Because they also have a second car dedicated for personal use.  But since the first car that they strictly use for business is technically not owned by the business, it is owned by the person's name, how can they claim 100% usage?  Or can they, as long as they keep all receipts?
