My husband and I always go back and forth about the maintenance of my car. Since he rarely drives it, he doesn't know when something's blinking or if there's a message saying the oil needs to be changed. I tell him when that stuff comes up, but if your husband's like mine, you know how that goes! We also try to do a lot of the maintenance ourselves (Well, my husband and dad do the maintenance!).
I'm making a copy for each of our cars and Ryan's motorcycle. Now there's no excuses!
