coolvegase34-- Maybe you should test drive the diesel and see for yourself. The thrust off the line as well as the midrange thrust is as if G-D himself is pushing you with all his force...it is amazing...and, this coming from a person who owns a GT-R which is the best performance car on the planet, especially for the money. And, considering it is a 4 door sedan, BMW has again pushed the handling to phenomenal levels! It is no GT-R, but it is pretty awesome.
Now, just check out the stats! 265 hp, and 425 lb feet of torque...most supercars do not have that much torque, especially from 1700 rpm.
As for the money spent, yes, you can not sneeze at $45k for the price of this loaded car, but, I have had cars costing 3x this price that gave me problems after a month of ownership. I am not happy about this, but, I am glad they caught this during the pdi and not as I am driving from the dealership!!!
I have faith that they will get it right...parts do fail sometimes, it happens.
