The reason not to buy is not that ridiculous when comparing it to a Ferrari or Lamborghini purchase. The car salesman could tell me “this huge scratch on the bonnet changes nothing, it drives anyway!” but I am still not taking it and buy a different brand.
I don´t pay 100$ for the Boeing-737-series as long as these screws are not fixed and in line 
but because this will probably never be fixed (I already discussed this topic in the PMDG forum) I have to wait for the next PMDG release and enjoy the wonderful Fenix in the meantime.
