Just completed a 3 week rental of an Azera Limited out of SFO. It listed on my receipt as G. My res was for an E.

It was a really nice upgrade. I had no idea what it was when I picked it up. By the time a turned it in I wanted to go out and buy one for myself. At 28K, it's a steal.

It was fast, comfortable, had XM, premium sound system, a sunroof, leather, a huge trunk, and great ergonomics. Way better than the junk I usually get that they call an upgrade.
