I didn't follow my own advice this morning as I was in a hurry. I reserved an F car from my local HLE with Satellite Radio. Received the only car left, a filthy Malibu with non functioning Sirius. Didn't realize until later on when it was warmer out that the car smells of smoke. Not horrible, but noticeable.
Based on this experience I cancelled next week's reservation with the HLE and will drive further and spend more in tax's and use the Hertz location at the COS airport. A real pain considering I live on the north end of Colorado Springs...
