Just wondering--- 1--Of the 75 total 512M made for our mkt, how many are in yellow? Is there any other color(s) besides red? 2--Does anyone know of the 75 512M original available, how many are left on the road today in the US? Just bought a 512TR after a brief search for a clean, no-story yellow 512M... In the near future, I will likely consider adding this to my collection.
