You can write off the actual cost per mile. It doesn't work out for me as I write off the work related fuel expense seperatly from mileage. If diesel is at $3.75/gallon, my pickup costs $.66 every mile. If you've got a semi inexpensive vehicle and it gets rediculous good mileage like a TDI Jetta, the amount you write off almost pays for the vehicle.

I've thought about buying my next boat with the company checkbook, stickering it up, but eek. I don't break any laws but an audit doesn't sound friendly. Maybe start a non-profit, then I can charge the cabinet shop the going rate for advertising. I wonder what BMO, or Alingy charge per area? That would be a good rate to use.
