My bosses boss does this, he has whatever the top Porsche SUV is. I think the monthly is 1950 or so and it's a total write off (though it probably shouldn't). When your gross is 300 mil a year I guess the IRS doesn't give a shit about say 25k of questions write offs a year.
I laugh a bit about it because I'm a car guy, and I think the car looks terrible and my much cheaper car is faster. Also funny because his entire car payment is more than I pay in mortgage, util, car finance (1.9% for a used car at a credit union) insurance and food a month. I was recently offered "overtime" to come help with another department that is getting slammed by being unexpectedly busy and I turned it down saying I don't need the money, I value my time off with wife/friends/family much higher than some money.
