Sole Proprietor Purchased a Vehicle - Need Posting Advice

My client is a sole proprietor.  He purchased a vehicle with sole proprietor funds and said he will be using it 50% for company and 50% for personal.  He also financed the purchase with payments coming out of his sole proprietor account.  He does not have an accountant.  He gets H & R Block to do his taxes.  How do I record this purchase?

Thank you.
