I am considering purchase of new 2013 Q5. I want one with MMI option, as I love it on my A4.

I am wondering - how much below sticker price are you able to negotiate?

Thanks!

$500 over invoice.

Depends on where you go, but I was able to get a 2013 Hybrid under invoice. I guess the fully loaded ones have more rooms to negotiate.

Q5 2014 Premium, light Package + panoramic sunroof - MMI
Pearl Black & beige interior
39k

Best I can get is 6% under MSRP.
Can anyone share where we can do better?

You have to time it around the time when they are coming out with the next model year.. so that they are more than willing (if not desperate) to move their prior year inventory. In the past I've gotten almost $10K off of MSRP when I went in at the right time. So if you aren't in the rush or if you don't care about buying a 2014 vs. 2015... I'd say you go for the 2014.
