For you lottery winners, the depreciation you can write off could be a major reason to purchase this car. I'm not a CPA, so you should check with your accountant, but since this is a SUV, it can qualify for a broader range of businesses where you can write off the depreciation. Depending on how aggressive you want to be, I believe you can write off up to 50% off the first year. Also the interest from any loan you have is also tax deductible. Add also the $7500 tax credit too. This is for a purchase. If you lease, you can only write off the lease payments and down payment. Not bad, but not as much as a purchase. Also the insurance, but that's the same for lease or purchase. Keep in mind that they have super low rates right now, so purchasing can be almost on par with leasing. Of course this depends on your credit and how much you want to put down.
