You will regret buying or working with Sheehan Cadillac. Very shady sales tactics, constant lies to the customer. Also, very little knowledge of vehicles. Once talking with the sales guys, you realize that they are just trying to push a sale through, with no regard to actually caring about the customer. In addition, they will tell you a car is available, have you fill out all the paperwork, run your credit, just to turn around at the last min and tell you someone else purchased that vehicle. Then of course they will try to put you in a more expensive car. This is an old tactic used by many dealers in hopes that you will still buy from them because they already ran your credit.
Lastly when speaking with the GM, Mark Metivier about how I intend to leave horrible reviews everywhere, he decided to threaten me telling me verbatim "We know where you live".
