After more analysis
The monthly payment on 35d and 50i are almost the same, with diesel being $6 more/month. I posted the details in the other thread on lease. Assuming, I can find a dealer to agree - that's critical!!

Fuel costs: with 12k/yr, MPG of 17 vs 25, fuel price of 3.87 vs 4.1, 50i will cost $65/month more or $2200 over the duration of lease. The difference does get my attention, but I am fine either way.

Frequency of fillups should be about a week vs 1.5 for the two. Availability of diesel - I need to research more about my area.

Fun to drive: this time around (in contrast to 5 yrs ago), I am so much certain about responsiveness, that both vehicles would be great. 50i will likely be intoxicating! Furthermore, sound of engine wasn't an important aspect for me, but now that I have heard on youtube and read more about it, the growl of V8 is cool!

Maintainence: Since I am leasing, shouldn't matter

Is there any other important criteria that I am missing?
