If the enhancements are physics, FFB, sound, accuracy and stability, it would be already a big thing for me personally. I always found the pCars games too "inaccurate" in their way of some design choices (except the setup screen, i just say diff, that is astonishing), but when playing pCars with a buddy, i always felt "i want this, but i want it to be different". Hard to explain. I always found the foundation(!) to be "amazing but horrible", maybe the "horrible" could be wiped out a lot.
