We are little over 300 members in the Pcar club here (just in Shanghai city) and the majority falls in this group of pre-2009. Seriously, we've never seen, never heard of an IMSB failure. In fact when you raise this ISMB thing here these guys are all looking at you like you are from planet lost. Same on the China-wide pcar forum (your PCA equivalent), never seen it being discussed. Interesting to see how figures differs from other regions.

Must the heavy smog found in air here that helps lubing of our bearings
