One way or the other, you have to pay for your own personal use of the vehicle.
My guess*** is that the better method is to have the lease in the business's name, the business makes the lease payments, and furthermore pays for gas and repairs with the business credit card. Then at the end of the year, figure out your business and personal mileage, and add the value of your personal use to your K-1 statement as taxable wages. That way, the business deducts 100% of the vehicle cost, and you pay tax on the value of your personal use, which essentially means you get personal use of the vehicle at roughly 1/3 it's actual value. It's less paperwork than an accountable plan.
***However, I am not a professional tax advisor and random internet advice is worth what you pay for it. You may want a professional opinion.
