Both trainings are good. The M Perfection training is on one of two race tracks in Germany -- Nurburgring Sprint track or Sachsenring and two others in Europe -- Spa-Franchorchamps (Belgium) and Hungaroring (Hungary).
The M Fascination Nordschleife is on the historic North Loop. I have done this training twice and could not recommend it higher. It is a once (twice) in a lifetime experience that is very rare on the world's most famous track. Think about it -- under what other circumstances would you be able to drive the Nordschleife in a 2-day closed session in an E92 M3 with professional instruction? Priceless!
Sign up quickly. Dates for 2013 were just posted online today at:
and the M Fascination Nordschleife training dates will likely sell out very fast.
Update: Dates posted as of 2/6/13 for 2013 are April 7-9 and April 9-11. New for 2013 is that the course is available in M6s (cost: 3650 Euros) or M3 coupes (cost: 2950 Euros).
Not posted yet are additonal dates that I have learned are available (and will be posted on February 13th at 9:00 a.m. Germany time):
April 25-27 and September 18-20.
