Other Car Rental Programs/Partners (ie. Alamo, Enterprise, Sixt) - What can I expect with a premium car at Alamo MIA?

Booked a premium class car with Alamo at Miami.

Just wondered what car I might expect?

Also any tips for getting a decent car at MIA?

I know very little about USA cars - so fear I may be given something poorer than the next person in line...

Thanks.

Look on the alamo website and tyhere is a tab marked cars and git gives as an example a Buick Lucerne. Normally a 6cly or larger engine with all the mods including cruise control.
