OK, here's what I did and I believe the math is correct however the numbers seem too attractive.
I put together a hypothetical scenario for an ED M3 E93, the only options I added were DCT and 19in wheels. Added destination and gas guzzler + 1000 dealer profit over invoice pricing. Putting up 7 MSDs lowered the MF to 0.00211 (0.0023 base + 0.0003 mark-up for ED - 0.00049 from the MSDs).
The totals came to 686.63 for a 36 month / 10000 lease
24 is not bad either, 733.86
Both are pre-tax but adding even 10% to the 36 month would still keep it under 800
The question is - would any dealer be willing to accept this or they would want higher profit and/or MF?
