Paul castle the owner of World of Motor Works that sells alot of buick parks ripped me off for 1,200.00 for a G N rear diff. I sent a cashiers check for it 3 months ago to this date I got no diff & he is not answering his phone so I have to fill a complaint with my local police dept. & they will send it to the bative police dept. so the D.A. can file theft charges aginst him. If anybody else has got ripped off by this guy e-mail me & then file a complaint at your local police dept. & you can be part of this complaint.
