Cool, thanks guys. We got these monthly planners so we keep track of mileage that way.
My main concern is parts. A few has suggested to me I should just submit the receipts and see if it works out (for extra wheels/tires, reasonable sounding items).. If it doesn't work then it doesn't work. If they plan on auditing me I'll always have my logs and paperwork to back up my business use %, etc.
I hear as long as I'm somewhere around 70-80% business use I should be fine.
Anyone else use their cars for business? I agree, the mileage adds up super fast.
If there's no more input.. guess I'll just call up my accountant.
