Anyone tried this out yet? What do you need to get the $4500 off on a new benz? Does different level of UA premier level matter?

The United Milage Plus is a approved "fleet" discount - and the "savings" changes depending on model and changes/updated each month... follow the website instructions to see updated fleet for the particular MB you are interested in .... print out the certificate ONLY when you are at the dealer confirming/purchasing the particular car.. remeber it's the Cert for the particular MB that "counts"...

 

So if you negotiated a 10% off MSRP , can you stack this "discount" on top of it?
