This is the Unfortunate Problem for Riders who do not own their Rides...One day you have them, the next day they've been sold straight after you've won the WEG's (with gold medal at 2012 olympics in sight) to the Germans!
So therefore - as long as Matthias dosnt own Toto there is always the possiblity of that happening to him....even more so as Totilas is now owned by a partnership.
