Also, I track my fill-ups with pen and paper and find the mileage the trip computer reports to be very optimistic.
I'm not saying that 360 miles/tank is impossible. I think that you can do it if you do a lot of highway driving at ~60 MPH. It would mean you're getting about 22.5 MPG and you'd be running the tank very low (not good for in-tank fuel pumps) and not driving the M3 in a way that justifies that fabulous V8.
For the record, I'm not saying that nvladik can't do it, but if he is consistently getting >22 MPG in his e9x M3 I would recommend he trade it on a 328i and save himself even more fuel.
