I will also add that while I am against cap cost reduction on a lease it does make sense to put a small amount down if the monthly payment in near the $50 level. Meaning, the security deposit is rounded to the next $50 increment (i.e. $500, $550, $600, etc), so if the cap reduction can lower the amount from $510 to $499 the security deposit would be $500. Therefore the max amount (7 MSD's plus regular) would be $4k vs. $4.4k. Obviously with an M3 the payment amount is usually higher and therefore the max contribution would be as well. But the math would still apply.
