I was at LAX a few times this past week and noticed that there are some nice cars to be found on the 5* and Gold lots. PC mostly ends up being pick your own color 300S, Altima, Maxima, while I saw some Infinitis, and even a couple Benz's in the 5* and Gold lots.
If you don't see anything good in the PC lot, I recommend doing a quick browse through the other lots and you might find something you'll like.
