Was there in July on a Thurs. mid-afternoon. Very few cars avail. We wanted one with XM and were willing to wait a while. The National staff was most kind in looking around in the return area, found a G6 with XM and within 5 minutes, had it washed and ready to drive out. I do agree that of all the majors, National is farthest out from PDX, but the great service made up for the bus ride.
