The Nissan dealer I purchased mine from was fantastic. I telephone and arranged a conveinient appointment for me to take the car for a lengthy test drive. They did not rush me or were not pushy like some dealerships I have come across in the past. They could have not have been any more helpful.
As others have said there are some great dealers and some really ropey ones, have a good look around in a certain radius to where you live. I'm sure you will get a better response from another dealer.
