Congrats on the first post … and more importantly congrats on the new car.
A few more pieces of info and we can answer your question:
X5 - which model?
What MF was used in your deal and what is the buy rate MF (can get from Edmunds). Any MF markup?
You took advantage of MSDs - very nice.
How much lease cash did BMW give you in your deal (varies by model)?
How much discount from invoice did the dealer give you. It looks like (adjust if necessary):
MSRP $69,070
Selling Price before any incentives $62,130.48 Pre-Incentive Discount 10.1% - thank your broker, nicely done.
