@Anonymous_ I've never been able to find anything that says you can't take the per-mile deduction after the vehicle is fully depreciated. I used the per-mile on my truck for about 15 years, and there's no question I fully depreciated it well before I sold the truck. Now when I sold it, I did use a cost basis of $0 since there was no doubt it was already fully depreciated. But even after fully depreciating it with the per-mile deduction, I found nothing saying I could not continue to use the full amount per-mile with the per-mile deduction.
