Hertz - Does US Presidents Club get Upgrades in UK?

Setting up a rental for this summer and I'm curious whether I can expect upgrades in the UK based on my US Presidents Club status. I would prefer to rent a lower class (cheaper) car if I could reasonably expect to get bumped up.

Thanks.

I'm going to Germany this summer and was wondering the same thing. I just qualified for PC for the first time this week http://www.flyertalk.com/forum/smile.gif
