Ok, I do really like the show so far... but there are some silly things happening...

You don't just order a "3-inch wide, two-foot long radiator hose and two clamps".

Well, no car is going to have a 3-inch diameter radiator hose; maybe a big tractor or semi-truck would have one that big... also, you wouldn't just use a regular piece of hose, you'd need a hose that formed for that car, so that it fits and doesn't interfere with anything, such as moving parts; it also can't rub on anything or else it wouldn't last.

Also, the girl compares knowing how to work on cars to changing a tire. Changing a tire isn't "working on a car"... And replacing a radiator hose is something that ANYONE who drives a car should be able to do without any training or experience whatsoever. If you can't do something that simple, you should just stay home forever...
