Can the LLC buy a vehicle? Yes.Can non-business use mileage be put on the vehicle? Yes.Is this a deductible as a business use of the vehicle? NO. Will the IRS have a problem with it? YES.
As long as they are listed on the insurance policy I don t see a problem with it. I would ask the person who owns the business though... If the family member gets in a wreck, the LLC may be liable...
