Car Lease Questions For Real Estate Business

[Russell Brazil]

I have two main questions. On a car lease is there a standard or accepted amount of the lease that can be applied to the business. Would 100% raise a red flag, 90/10, 80/20? (Should I track mileage to make the proper assignment?)

Also if I were to prepay the entire term of the lease at once, could I apply that to the single years taxes, or does it need to be taken over the course of the whole lease (3 years)?
