Ask for a bigger discount? Ask for buy rate MF? They are giving you all the rebates as expected. Autopia just listed a i4 35e with a 4% discount off MSRP on a unit with a bunch of options.
edit: Looks like the MF went up for this month to .00210 for the i4 35e / 40e, so if the quote is from today then you might be seeing that number + a little padding for finance.
