I just ordered a new diesel X5. I got the $4500 off from BMW USA, plus negotiated 4.25% off of MSRP. Is this a good deal? Should I go to some other dealerships and see if I can get a better deal? The dealer I'm dealing with say that they have a 6% margin and that 4.25% off of MSRP is pretty much unheard of for the 3.5d, given its popularity and that it's a new model. Are they BSing me?

Total MSRP was $75K, so with the 4.25% off and $4500 from BMW plus the tax credit of $900 it worked out to about $8,500 off.

Just wondering if you experts out there can give me any advice. The vehicle looks like it's gonna be sweet!
