OP,
I have an accountant. I am also a business owner who makes well over the amount that Obama considers the upper 5% of the population. I also live in the S.F. Bay Area. So, I'm in the same boat as you.

Regarding my tax comment to you, that was why I mentioned/asked whether that $45k was the total taxable bonus you received or was it your actual tax savings. Because, if it is the former, then you would be taxed on that $45k and it doesn't mean that buying the car "saved" you $45k that would have gone to the IRS.

By the way, are you incorporated? If so, did you purchase the car under the corporate name and insure the car under the corporation?

And, I don't know why you're getting belligerent with me. I thought my post was rather cordial.
