OP, despite what the majority of responders have said, I respectfully disagree.
Life comes once, ANYTHING could happen to you. Enjoy driving an amazing car asap.
Don't err on the side of caution, planning to win the long game, (ie- comfortably payoff the mortgage, have $$ for a huge wedding, 2.5 kids to make it to affluent schools, furnish home comfortably, etc) and never seize the chance to have a sweet ride while young enough to really enjoy it.
Coming out of pharmacy school (which is now 6 years+ @ 35-45k a year at an average university) I saved a year or two and got a mortgage and a m3. You can't take money with you when its over.
I know before anyone says it, yes pharmacy pays better out of the gate, but MD,DDS, surgeons and other specialties completely DESTROY our 150ishk/year after a few years of practice.
GO FOR IT OP!
850-900ish a month for an m3 lease!
