I don't think you realize what a lightly modded gt-r delivers (intake & exhaust)... its nearly on par with an ess vt-2 625 dct m3. I know as I've roll raced enough of them. An E85 tune alone on a gt-r places it in sc'd m3 land.
Lots of videos out there...the gt-r defies physics.
As for daily driver...things rattle, cabin noise, feels detached, etc. The m3 is a much more well rounded car.
