Audi Club
 

This sounded like a no-brainer after I read about it: you join for $49 (one year membership) - you then get back $500 after you have bene a member for six months. OK - I was going to order a 2013 A6 in the late summer/early Fall and - hopefully have it delivered in November or December and I will get $451 taken off the price of the car.

You get a rebate and they also have many interesting activities.
