Hertz - EDI fleet question... Green Collection diesels

I reserved a car at EDI for a couple days... I went with the full-size diesel (manual transmission), since it cost the same as a mid-size petrol car thanks to my AAA discount. Does anyone know which models of diesels Hertz has at EDI?

I also noted something a little strange with the vehicle type. It states:

Vehicle Type
Full Size - Green Collection
intermediate 4dr manual

So... is it a full-size, or an intermediate?

Thanks...
