Received: Sebring Convertible, 27k... (Too bad the convertible part was broken!)
Location: SAT
Status: AVIS First
Reserved: Mid-Size
Received: 2009 Pontiac G6 with 1100 Miles on it. OK, technically not an upgrade, but actually was quite nice, still with "new car" smell, and XM, which is always appreciated.
