I was hoping I would have the same results, but no such luck...

Location: IAH
Day/Time: 2/9 around 5pm
Status: Presidents Club
Reserved: Premium Size
Offered: Nissan Rouge
Given: Sebring

Flight arrived about 20 minutes early and the board said CTR. Go to the counter and they say that they are out of premium cars and that they will give me the Rouge at the full size rate. Hesitantly, I agree (after asking for one of the couple CTS's sitting out front and being rejected).

Rouge had no XM and the power outlet was not functional (only 1,000) miles.

Went back in to the desk and let them know the car was not acceptable. Again, asked about the CTS and was told that they were reserved for CEO's (I am guessing they meant Chairman Club).

Was given the Sebring, which luckily has XM radio. Funny enough, the outlet in the ashtray doesn't work. Luckily there is another one in the center compartment.

When exiting the Avis facility I saw a couple more Cadillacs sitting around the corner. I guess those cars weren't available either.
