I had to take my mother this afternoon to pick up her new eyeglasses. She can't get in my 300M, so we took the Olds van. As we were driving through town I looked up at the overhead console and the thermometer said 118F. That's the highest temp I've ever seen on that thermometer. When we got back I checked the thermometer in the back yard and it said 112F, so that 118F on a busy and hot city street was probably correct.
