Williams Chevrolet

I am a disabled vet and bought a 1999 monte carlo from williams chevrolet in Traverse City, After getting it home i smelled antifreeze and the speedometer didnt work after i drove it for a few miles. I called the sales man told him what i had found he told me to wait till the bumper to bumper warrenty kicked in after 30 days. I kept complaining and finaly after 3 weeks they took it in and looked at it, told me the front wheel bearings were bad the rear tires were bad needs transmission flushed and new filters and the i was leaking antifreeze.They did fix the bearings and the speedometer after 2 months of complaining. I kept after them about the leak and they told me all they could do was sell me another car but they wernt going to fix it, The car is my life line to getting me therapy for cancer witch i had told them thats why i need a depenable car I think someone should look into these practices and put a stop to it.
