Contacted them for a motor for my 99 Suburban. When it was recieved it was an earlier motor that was not compaible and even illegal to install for emissions requirements. Contacted customer service and was told not their problem. When I tried to explain details customer service agent refused to listen and told me if I wanted to return it was my problem and at my expense. Very rude and short. Obviously had inferiority issues. Will never use them again and will tell everyone I see not to trust them.
