Are the "intruments" (whatever that may be) worth 6000€?
Anyone have any info on what these instruments are?
Why would a manufacturer want its engines (weighing 150kg a piece) back at every replacement? Are the engines sent back to Diamond USA or shipped to Vienna?
Anyone has info about the reliability of the 2.0 engines?
