Lets just say a "friend" did this... He is working on it... It is no accident or mistake. It was done on purpose...
If it was malicious, that's just evil from what appears to be another buick guy. I have dealt with companies that have had their domain names taken by consultants. It is fairly easy to get it back but, the legal fallout against the person that takes it is not pretty. I hope that is not the case here.
