BWI definitely is hit or miss. The last two times I have rented from there (both within the last month), the Executive Selection was comprised mostly of Impalas and regular Grand Prix. On one occassion, there was a new 4Runner and a couple of Envoys, and on another, there were only small SUV's in addtion to the Impalas/Grand Prix. On both occassions, I was fortunate enough that they pulled a Volvo S60 into the Executive Selection just as I was about to give up and select another car.
