I will say this dealership is the definition of your stereotypical used car dealership. If you want a deal full of hassle, and a deal that is difficult in every sense then shop at Westborough GMC. I have bought a lot of vehicles in my day and I know how it works. This is by far the worst dealer I have ever dealt with. It makes me not only never want to buy a GMC again, I may never buy an American car again.
I work in the customer service business and live by the words, "the customer is always right." I don't think anyone but the one girl in service has even heard this phrase, never mind care about it at all.
