I know Audi gave 5% discount on most of their models for ED. Are there a ED invoice just like BMW where we can use it as a starting point?

take 5% off the MSRP price for starters. That is how we did it anyways. I hope this answers your question as I am not familiar with BMW's ED.

BMW has a ED MSRP and as well as a ED invoice.

ED MSRP is 7% off US MSRP plus a lot of Bimmerfest member can get 1000 over the ED invoice where is another couple thousand dollars savings off ED MSRP.

u don't need to pay 750 destination charge if u do ED with Audi. Not sure about BMW

Due to allocation and other issues alot of BMW dealers will sell the ED car for $1k over ED invoce plus $750 shipping. I just got an ED quote on a BMW 535i. The net cost to me before the BMW club rebate of $1K was a little over 12% discount. Under the best of negotiations, Audi is not competitive on price for ED.

The US MSRP on my car was $44,900 and the selling price was $39,610, which is almost 11.8% off MSRP. Both prices include the standard $775 destination charge. If Audi doesn't charge destination, that brings the savings up from 5% to almsot 7% on a $40K car.

If one could negotiate a couple percent more off the MSRP, the Audi program would be competitive with BMW.
