If you can find out which GM dealer is the local parts distr
for the area, IE They supply other GM Dealer PArts dept's,
They will usually sell cheaper, Also, make up a bussiness name, that helps reduce price...
I tell them I'm Incorporated in another state , therefore pay
the state sales tax ( I pay in cash ), I have been getting GM parts cheaper than NAPA...
