Should I advertise car as towable?

I'd offer it at an additional cost, then play it by ear on who answers the ad. Of bigger note is the mileage that shows on the odometer from towing. I would think an odo that registers higher than the actual engine run time would be an advantage to any buyer as the over all wear on the vehicle would be less than the odometer states.
But maybe the odo doesn't record towed miles. In that case, never mind.
