Need opinions

I live and work in Germany for almost a year, the past year has been rough since during the week I live and work in Berlin, and on the weekends I travel about 250km on Friday to stay the weekend at my family's, then 250km back on Sunday night.

Public transportation takes about 6 hours a direction because of train connections and such.

I get paid roughly 2500€ a month(Netto), my current expenses are ~800€ rent and about ~400€ on food, other stuff like bills and such is another ~200€.

My question is would it be logical to go for a "Dream car"? I've visited a Mercedes dealer in Berlin and found a deal on a C43 AMG T-Modell(Estate). The car is a 09/2018, and they want 42000€ for it.

I am planning on leasing it which comes down to about ~580€ a month in car payment(I have to least because im on a temporary work contract lasting for ~4 years after which I plan on them buying the car back from me) although that is if I take 36 payments(Might extand to 48) and whatever insurance is gonna be.

Would this be a logical financial decision? On the one hand im gonna sort of slave for the car, on the other hand I get to drive something I never even dreamed of having.

Looking forward for honest opinions and rational. Much love.
