I want to order a 2015 S5, but I'm confused about placing an order when no pricing is available yet. How do you get the best price from various local dealers when the MSRP and invoice prices are unknown?

I've emailed a number of dealers and had offers for as much as 6% off MSRP down to only $500 off MSRP. The 2014s seemed to have a markup of over 7%.

How can you haggle without knowing the pricing?

You can negotiate a percentage off the MSRP (Manufacturer Suggested Retail Price), which is standard throughout the US. Only differences would be taxes and delivery fee. Audi Club members automatically qualify for 6% off if a member for six months. Audi Owner Loyalty is also available for current Audi owners and BMW, Lexus, Mercedes, Acura, or Infiniti, for models back to 2001. It is $1000 for the S5 in addition to the Audi Club offer. European Delivery also gives 5% off MSRP. I don't think you can combine the Audi Club 6%, European Delivery 5%, and Audi Owner Loyalty $1000, but who knows?

When I purchased my 2013 S5 in August 2012, I received the European Delivery 5% off, the Audi Club discount (at that time a fixed amount), and the Audi Owner Loyalty $1000. Lots of amenities while in Europe.

I have found it to be very accurate and a great lever when bargaining.

$1k over invoice for 2015 model seems reasonable.
