We had a great experience when buying a car from the dealership, until the end.  They added service contract, and paint shield plan without my request or permission.  We were advised during the test drive there were 2 keys for the car, but when we took delivery the second key could not be found, and they refused to honor what we were told during the sales pitch, because we didn't have it in written into the contract.  We were told that the 2nd key was there with the cars documents so how would we have known to have them write a replacement key into the contract?  That changed my opinion of the Sanderson name.
