Hertz - Prestige collection in NYC

I'm trying to book a Prestige collection car (either the X-Type or S80) from any LGA/EWR/Manhattan location, and I can't see it on the list of available car types. Has anyone booked a Prestige car in the NY-area.

yep, got one last weekend in midtown .. on w 55th st. the service was ****ty, but they had a great selection of jags, and lincolns
