Very interesting to see that your first post is on such a subjects as defending c people as Mr Otto V who least said have a bad reputation. First question comes to mind is this perhaps Otto himself or does this dude don't want his friends to know he's doing this.
There are several stories out in the open of people washing Learjets for over a year without getting a single hour on the plane...This happened to an old friend of mine as well. And there have been enough articles in his homeland about this guy unfortunately these are in Dutch and not suitable to post on an English Board.
Doing a quick background check (chamber of commerce) and I must admit I couldn't find any company at the address of his website.
