I live about 2 hours from the Performance Center (maybe only good reason to live in SC) and have done PCD, M School and Advanced M school at Virginia International Raceway and Carolina Motorsports Park. No other track time besides BMW schools so nothing to compare it to.
PCD is fun because you are getting your own car and the factory tour but not much track time relative to the others.
M School is great because of all the track time in M cars but track at PC a little small. It is a prerequisite for the advanced school
Advanced M school at VIR is the best and would rec to anyone. 3.2 mile track is awesome and we constantly reached 140+ mph in M6 and M3 doing lead follow laps. I am no videographer but this is the video from VIR.
One year ago today we we put on a corporate event at CMP.
Should give a little comparison to the PC.
