My dad has the BMW on the jacks now. A couple nights ago, he took off the exhaust as he began his work underneath. He called several of us outside without telling what he was doing. I saw the pipe on the ground around the back of the car and knew what he was doing. He started the car and an echoing roar when sweeping down the street and back, resounding off the neighbors' houses and into the woods. It's not often when my family is the ones making deafening noises at night.
