I am looking to do a factory build for a 2016 CLS 550.
MSRP for my factory build $86,300

I am gathering offers from several dealers and one offered $76,290.00 + tax, tag, and fees.

Thats about an 11.6% discount.

Does that sound like a good deal?

For factory build do they discount that much (or do they usually give such discounts for inventory new cars)?

Should I be cautious of what tax, tag, and "fees" they will try to add?
What are considered usual/normal fees, and which fees are unnecessary?

Any advice is most welcomed.
