If the agent doesn't mention the 50% scheme, then it should be for the OP's taking. If they say "Normally it's $70 per day to upgrade to this PT Cruiser, but you get 50% off!" then the OP should keep negotiating, naturally.
Don't know how widely known the policy is, though, so such usage may get the OP laughed at by the sales agent.
I did find the official verbiage, though, so the OP could print this and bring it along:
50% off Upgrade Rates *
Blue Chip Members receive 50% off any upgrade. The next time you are picking up your rental, save money AND go for luxury by upgrading from your standard rental choice. Just Ask your Blue Chip Rental Counter Agent what is available – they’ll be happy to accommodate your request! It’s just that simple.*(This benefit is in conjunction with non-corporate / non-government rentals.)
