Pub 544 not final yet.  ProSeries is wanting me to a like-kind exchange, but tax reform states only real property is used for Form 8824.  Should I calculate the business use percentage for all years, the mileage depreciation rate for ALL miles since it's a luxury vehicle, and enter on the "enterable" Form 4797 and Sch D as applicable to figure gain/loss?  Then enter the full purchase price of the new vehicle on the Car/Truck worksheet?
