these people are criminals. the floor manager "mr.thirsty" has his people tell you anythin you want to hear to get your down to their dealership. they then run thier numbers in ways that should be illegal. quoting absurd monthly payments with a large down payment but wont tell you what APR or how long of a term before trying to get your ok to draw up paperwork. refuses to do anything with selling used or certified preowned vehicles, even upon request. these people need to be criminally charged with fraud.
this dealership has a horrid reputation within its own corporation as well. gmc would do well to save face and shut these ppl down.
