There might have been some kind of arrangement between dealer and seller to give a good PPI. You should have got the PPI done by somebody completely independent.
Perhaps you can take that POS Buick back and exchange it for something else on the lot. Being buyer beware you are stuck with that pos unless you get creative.
Make up a placard that says this business sells lemons and walk in front of the business
on a Saturday. A girlfriend of my first wife did that and got satisfaction.
