In the case of the toaster they are for more than just looks. Twice last summer I left the windows cracked and it rained. The 1st time the seats were wet I just figured the wind blew the rain in. But after the 2nd time having wet seats and a puddle on the floor mats I realized that the nearly vertical windows and the way the door seal is that any rain that comes off the top will just flow directly into the open window. The in channel design should allow the rain to just drip off the edge of the vent.
It takes me about 20 minutes this time of the year to cool off and stop sweating after I run. I heat the garage to about 55 degrees so it's a good place to cool off without getting uncomfortable during the in process. In the summer it takes like an hour before I cool off. The AC in the garage and the fan I have out there help the summer.
I use this cool off time to clean up whichever vehicle I drove last. I have a California Car Duster and it keeps them looking good between washings assuming I avoid mud and wet roads. I've been known to stay home and not go somewhere because the roads were wet. I really like a clean car and I have to say it pains me if my car gets dirty too quick after I wash it. I clean the brake dust from the rims also during the cool down time. I tried some of that wheel spray that is supposed to prevent the brake dust from accumulating. Nope still accumulates. I also spray the tire black stuff on then clean the over spray from the rims. That one cleaning takes care of both the brake dust and tire spray.
If by chance I have not drove either vehicle then I use the cool off time to put up tools and do general garage clean up. I'm way behind and I really need to be spending extra time cleaning the garage before JB gets here next week. 4-5 hours should put the garage right.
