Well in our area all farmers drive big fancy trucks and run them into the ground hauling animals, feed, etc.. And they have to drive on the interstate to get places. Not uncommon to spend over 1/2 million on a combine that comes stock with gps farming systems, ac and a descent sound systems. Is that extravagant and doesn't meet deductible standards ? Hell we have farmers with multiple thousands of acres. Sell millions in crops and animals each year. If I said you can not depreciate your 1/2 million combine with a stereo system or your Ford F450 extended cab with leather seats because they are too extravagant, I would get prodded with a pig sticker !!!! If its not 100% farm use, give them a percentage.
