I found this and it works perfect for my classic and vintage vehicles that don’t have cup holders. No, it’s not what you think- try 1983 Escort. The economy is tough and it’s paid off.  It. Does. Not. Leak. Or. Spill. Anything.   I drove past it twice a day for almost  two weeks- it was sitting in the ditch of a county road so I grabbed it, took it home and cleaned it up. It likely fell off of somebody’s flatbed when they were checking their cattle on cornstalks but despite the dent, it’s pretty good. I don’t know how this was taken care of  before I found it but I don’t know if it keeps this warm for 7-8 hours, especially if you are outside. I took it hunting and it was nice just to shove in a pocket someplace and have something warmish to drink all morning.
