Other Car Rental Programs/Partners (ie. Alamo, Enterprise, Sixt) - Alamo/National Luxury Class Question?

Got me a rental for a week out of PBI in FL for a Luxury for Alamo and National for 160.00 a week. What are the options for a Luxury Car? A know a DTS is an option what else do they have in that class?

Very rarely anything else besides DTS'. Ive spotted a few CTS and SRX over the years and sometimes you'll run into a 300C Touring, but thats about it....

ATL does have a couple of 300s and CTSs in that class along with the ubiquitous DTS.
