If you're a Premier member of United MileagePlus, you can save up to $5,000 on a new Mercedes-Benz, and if you purchase a 2014 CLS-Class or E-Class Mercedes, you'll get 25,000 bonus miles.
The bonus mileage offer and incentives are only available to members who are MileagePlus Premier members at the time of an eligible transaction.
To receive the miles or incentives, the MileagePlus Premier member must log in to http://www.united.com/mercedes using their MileagePlus credentials and print out a Savings Certificate to present to the car dealer.
The mileage offer is valid only on a new vehicle purchase or lease of any 2014 E-Class and any 2014 CLS-Class through Sept. 3, 2013.
These offers are not valid for any purchases already completed and a member may only take advantage of the offers one time per calendar year.
