Been there, done that. I drove a Jeep Wrangler for five years.
I remember my old Baja Bug (what a blast)...
I had a transformer hooked up to a blow dryer. I epoxied a magnet onto the bottom of the blow dryer handle. I’d plug the transformer into the cigarette lighter...
Viola! Heat!...or CUSTOM DIRECTED DEFROST!
(Had to adjust the idle to really fast, because it would SUCK the battery dry.)
Think waaaay back to your first couple of cars....if you are like me, they kicked butt, regardless of what shape they were in. I’d tolerate little inperfections that would drive me bonkers today.
