I don't mean to attack you, but is there a reason for leasing the car?From putting away SEP contributions to doing target benefit or defined benefit plans, to leased car expenses that include all your maintenance, to *, there is enough already. Once it is on my personal return it is as clean as can be.
My friend's parents own a business and the business owns a minivan. Officially it's for company business, but it's used for personal stuff too. From the way they explained it, it sounded like they can write off most gasoline and all maintenance, but they will need to pay income tax when the van is sold. It's a 1991 GM Safari and it's still doing company business. They use it for hauling around small amounts of tools or small parts that would be used by a heavy duty mechanic.
