I have a luxury rental this next month at PIT and I am wondering what the mix at National has been looking like this past year...I usually rent Luxury class but have not rented much from National this past year...

I have noticed the few times I have that I saw a ton of Chrysler 300's which I do not like...I like the Caddy's much better...At Avis they finally took the 300 off the Luxury list but see mostly Town Cars there...My question is are there not many Caddy's around anymore? Or does National have just Town Car's and 300's mostly? If anyone could give me an idea of what they have been seeing as of late...And if I got a 300 or Town Car does National let you switch out cars if I found a Caddy at another location if im traveling to another city...Avis never seemed to mind me switching out cars at different locations...
